Experimental and parametric study on seismic performance study of column mid-height uplift steel rocking frame

Structural overturning due to second-order effects presents a significant challenge in the design of uplift rocking frames, particularly in high-seismic regions. Existing configurations, which typically locate the uplift joint at the base of the column, exacerbate this issue by increasing rocking demands. While various solutions have been proposed to address this limitation, a design that effectively mitigates these risks while maintaining energy dissipation(ED) and self-centering capabilities remains underexplored. In response to this challenge, this study introduces a novel column mid-height uplift steel rocking frame (CMURF) that relocates the uplift joint to the mid-height of the first-story columns, restoring the column foot to a fixed condition. This design induces reverse curvature bending in the upper and lower segments of the columns, effectively reducing rocking demands and the associated risk of structural overturning. To validate this concept, a half-scale, single-span, three-story CMURF specimen was subjected to cyclic loading tests. Subsequently, 20 detailed full-scale finite element models (FEMs) were developed in ABAQUS to assess the effects of varying key parameters, such as height, span, initial prestress of steel strands, and the quantity and arrangement of LYP225 steel web hourglass-shaped pin dampers (LYP-WHP), on the seismic performance of the frame. The results demonstrate that the CMURF exhibits a characteristic double-flag hysteresis shape, indicating strong self-centering performance. Additionally, the specimen demonstrated sufficient lateral stiffness, bearing capacity, and effective control of residual deformation, with the LYP-WHP providing stable ED capabilities. The findings indicated that CMURF offers a promising solution for mitigating structural overturning risks in rocking frames while preserving critical seismic performance features. Key parameters, such as height and span, significantly influence performance, with taller structures experiencing reduced self-centering ability and seismic resilience, while larger spans improve both. The initial prestress of the steel strands primarily affects self-centering, while the configuration of LYP-WHP impacts ED. Optimal design recommendations include a self-centering coefficient between 1.52 and 2.45 and a height-to-span ratio between 1.13 and 3.63.

Study on physical, electrical, magnetic and energy harvesting performances of eco-friendly piezoelectric ceramics (1 − x)[0.995BNKT–0.005LN]–xFe2O3 complex system

ABSTRACT In this work, the complex lead-free piezoelectric ceramics with formula (1 − x)[0.995 Bi0.5(Na0.80K0.20)0.5TiO3–0.005LiNbO3]–xFe2O3, where x = 0, 0.010, 0.015 and 0.020 mol fraction, have been prepared via a conventional solid-state method. The effects of Fe2O3 doping on the physical, microstructural electrical, energy harvesting and magnetic properties have been systematically investigated. All ceramics were sintered at 1150°C for 2 hours with obtained relative density of ~ 96-97%. The XRD and Raman data revealed the coexisting rhombohedral and tetragonal phases for all samples. SEM image presented angular grain packing with the average grain size range of 0.43–1.03 μm. The addition of Fe2O3 content improved in electrical properties of undoped sample particularly at a composition of x = 0.015. The maximum values of ε m = 6250, S max = 0.29, d*33 = 578 pm/V, d 33 = 211 pC/N and FOM = 3.54. All ceramics indicated ferromagnetic behavior with slim hysteresis shape. The results suggest a potential for its applications as an eco-friendly compound for further use in sensor, spintronic and microelectronic devices applications.

Inferring sediment-discharge event types in an Alpine catchment from sub-daily time series

Abstract. Fluvial sediment dynamics in mountain rivers are changing rapidly in a degrading cryosphere, raising the potential for erosive rainfall and runoff and detrimental effects on downstream areas. Hence, we need to understand better what characterises and drives episodic pulses of water and suspended solids in rivers. Here, we infer different types of such sediment-discharge events from 959 automatically detected events based on 16 metrics derived from 15 min time series of streamflow and suspended sediment concentrations from Vent–Rofental in the high Ötztal Alps, Austria. We use principal component analysis to extract uncorrelated event characteristics and cluster event types with a Gaussian mixture model. We interpret the thus inferred event types with catchment metrics describing antecedent conditions, hydrometeorological forcing, and fraction of catchment area with freezing temperatures and snow cover. We find event magnitude, hysteresis, and event shape complexity to be the main factors characterising the overall event regime. The most important characteristics distinguishing the event types are suspended sediment and streamflow magnitude and complexity of the hydro- and sedigraphs. Sediment-discharge hysteresis is less relevant for discerning event types. We derive four event types that we attribute to (1) compound rainfall–melt extremes, (2) glacier and seasonal snowmelt, (3) freeze–thaw-modulated snowmelt and precipitation events, and (4) late-season glacier melt. Glacier and snowmelt events driven by warm conditions and high insolation were the most frequent and contributed some 40 % to annual suspended sediment yield on average; compound rainfall–melt extremes were the rarest but contributed the second-highest proportion (26 %). Our approach represents a reproducible method for objectively estimating the variety of event-scale suspended sediment transport conditions in mountain rivers, which can provide insights into the contribution of different drivers to annual sediment yields in current and future regimes. Our findings highlight the importance of both meltwater and rainfall–runoff as drivers of high-magnitude suspended sediment fluxes in mountain rivers.

Photonic fan-out and local selectable inversion of the optical hysteresis shape

We demonstrate and elucidate the local selectable inversion of the hysteresis shape of a bistable optical signal after fan-out. This selectability is based on a hysteresis-shape transformation that yields a switching contrast over 20 dB in magnitude for both the inversion clockwise (CW) and the non-inversion counterclockwise (CCW) hysteresis shapes, while maintaining input-switching powers. This behavior leverages an initial signal whose bistability is manifested by its state of polarization; a generalized Malus’ law elucidates how selection is possible by controlling the transmittivity hysteresis through each local polarizer. The concept is demonstrated using a Fabry–Pérot semiconductor optical amplifier to produce the initial bistable polarization-rotating signal, followed by a 1 × 2 fan-out and the realization of all four hysteresis shapes at each location, independent of the other location. This fan-out and selectable inversion behavior is applicable to other nonlinear photonic systems and provides new functionality for parallel optical processing.

Biophysical Drivers of Seasonal Hysteresis of Urban Heat Islands Across Climates and Urban Landscapes

AbstractThe phenomenon of seasonal hysteresis between urban heat islands (UHIs) and background surface temperature was reported in many studies, but a unifying explanation for the causes of its magnitude, shape and looping direction remained less clear, and the impacts of urban landscapes and background climate on such hysteresis were also the subject of enquiry. Here we performed a systematic study based on a long‐term offline simulation for surface energy budgets, surface air and skin temperature of the urban‐biosphere system in East China. It was carried out with an up‐to‐date land surface model — the CLM5‐LCZs (the Community Land Model version 5 (CLM5) coupled with a newly developed urban canopy model representing diverse urban landscapes with the local climate zones classification scheme). To isolate the causes of UHIs hysteresis, a simplified framework was constructed by combining a mathematical representation of grid/subgrid model outputs, the two‐resistance mechanism method and the time‐lagged cross correlation analysis. The results exhibited distinct hysteresis patterns of UHIs such as twisted, concave‐down, concave‐up and convex‐up curve across diverse background climates and urban landscapes. The basic shapes of hysteresis depict a gradual transition from concave/convex‐up to concave/convex‐down by characterized by a larger winter UHIs from a wetter and warmer climate to a drier and colder climate. Magnitude and seasonality of surface UHIs are separately dominated by the urban‐rural contrast of evapotranspiration and heat storage at daytime and nighttime, whereas across‐climate variations of daytime and nighttime surface UHIs hysteresis are regulated by the phase shift of convection efficiency and anthropogenic heat. Urban landscapes affect the hysteresis mainly by altering the amplitude rather than the shape of looping curves. Our work could provide a fuller picture of how to mitigate urban warming considering inter‐seasonal tradeoffs over a broader region.

The 20-nuclearity compound [Fe8Dy12(tea)8(teaH)12(NO3)12]·8MeCN (where teaH3 = triethanolamine) was synthesised and characterised through single crystal X-ray diffraction and magnetic measurements. The shape of the magnetic hysteresis in the microSQUID measurements was rationalised using the MAGELLAN program.

Seismic displacement response of SDOF systems with SMA slip friction dampers

Owing to superelastic behavior, shape memory alloy (SMA) has been widely utilized to develop self-centering damping devices. Recently, the authors developed a novel SMA damper, i.e. the SMA slip friction (SMASF) damper. The cyclic behavior of the SMASF damper not only depends on the hysteresis shape factors of SMA bars, but also on the coefficient of kinetic friction and the slope of the friction plates. Hence, the basic working mechanism of the SMASF damper is different from that of conventional SMA dampers. In the early work, the features of the SMASF damper have been revealed by static cyclic loading tests. However, the seismic displacement responses of this novel damper remain unknown. To this end, this paper initiates with a brief introduction of the damper, including the configuration, working mechanism, and testing results. And then, extensive seismic analyses based on single-degree-of-freedom systems were conducted. Based on the constant-strength ductility demand spectra, the displacement responses of the SMASF damper were understood through the comparisons with conventional SMA damper and friction damper. A wide range of fundamental periods, strength capacities and seismic intensity levels were considered. Further, parametric analysis was conducted to assess the effect of the hysteresis shape factors of SMA bars and the coefficient of kinetic friction and the slope of the friction plates. This study also sheds light on the force-based seismic design method for this damper.

Experimental investigation of deficient RC frames retrofitted by RSFJ-toggle bracing systems

This paper investigates the performance of the new retrofitting system, consisting of self-centreing damper resilient slip friction joint (RSFJ)-toggle bracing system. The RSFJ-toggle bracing system can be activated within small drift values of the frame and preserve the frame from excessive damage. Two scaled deficient RC frames representing typical pre-1970s RC moment resisting frames were constructed and tested to investigate the performance of such retrofitting system. Material testing of the concrete and steel rebars as well as the damper component testing were conducted and recommendations regarding the proper design of various aspects of this retrofitting system were provided. The experimental observations demonstrate the improved behaviour of the frame in terms of energy dissipation and enhanced stiffness and strength for the upgraded RC frame. As per the findings of this study, the proposed retrofit solution can strengthen the frames within a limited drift and improve the frame’s damping with a repeatable semi-flag shape hysteresis performance.

Electric field and temperature dependent ferroelectric behavior of Bi0.5Na0.5TiO3–Bi0.5K0·5TiO3–BiMg0.5Ti0.5O3 piezoceramics

The ferroelectric (FE) hysteresis behavior of solid state synthesized 72.5Bi0.5Na0.5TiO3-22.5Bi0.5K0.5TiO3–5BiMg0.5Ti0.5O3 ceramics were studied at different electric field amplitudes (E0) and temperatures (T). The three-stage dynamic behavior was identified on the basis of hysteresis shape in different E0 regions (stage I: 0 <E0 < 8.7 kV/cm, stage II: 8.7 <E0 < 39.2 kV/cm, stage III: 39.2 <E0 < 68 kV/cm). The variation in electro-strain (S) with E0 also support the same and indicates a correlation between S and polarization (P), which was further confirmed by dS/dP vs E0 and S vs P2 plot. The T dependent FE and electro-strain loops was investigated at 55 kV/cm in 25 °C–180 °C. On the basis of its hysteresis shape, the FE loops were grouped into three T regimes, i.e., (i) 25 °C–70 °C (ii) 80 °C–120 °C and (iii) 130 °C–180 °C.

Diverse seasonal hysteresis of surface urban heat islands across Chinese cities: Patterns and drivers

Understanding the seasonality of, and contributors to, surface urban heat island (SUHI) will pave the way for developing more generalized urban cooling strategies. The direction and shape of SUHI seasonal hysteresis have been thought to be background climate dependent. However, there remains a relative paucity of knowledge about the patterns and driving mechanisms of such hysteretic phenomena across diverse climates. Here we show that the seasonal hysteretic cycles of SUHI in the daytime and nighttime across Chinese cities between 2003 and 2020 can be identified as eight and six primary patterns, characterized by diverse and complex behaviors including clockwise, anti-clockwise, twisted, concave, and convex directions/loops. The urban-rural differences in evapotranspiration (ΔET) and surface albedo (ΔABD) have been recognized as the primary contributors to SUHI in the daytime and nighttime and their seasonal hysteresis, respectively, as measured by structural equation modeling (SEM) and time lead/lag analysis. These biophysical mechanisms for diverse seasonal hysteretic cycles of SUHI in China re-emphasized climate context dependencies in SUHI terms. Furthermore, the observed divergence of SUHI hysteresis typologies within similar background climates highlighted the additional drivers of complex urban systems because SUHI is a combined result of rural background and urban characteristics. We conclude that the cost-effective UHI mitigation strategies creating synergies or avoiding trade-offs among seasons should be climate context-specific and tailored to local urbanicity.

Influence of the anchorage shear hysteresis on the seismic response of nonstructural components in RC buildings

This article presents a numerical study on the influence of the anchorage shear hysteresis on the seismic response of nonstructural components (NSC) connected to multi-storey reinforced concrete (RC) buildings, and of the anchorage itself. To cover a variety of different types of shear hysteresis shapes, this contribution considered the experimental results obtained for five types of post-installed anchors. The results were used for calibrating the hysteresis model of the anchorage connecting an ideal NSC with rigid fixture and a 12-storey RC building host-structure. Using a suit of 40 earthquake records and assuming a single NSC at each storey level anchored by a single fastener, a series of non-linear dynamic analyses of the structure-fastener-nonstructural system was carried out. The results showed significant differences in terms of maximum acceleration and force of the NSC and anchorage, respectively, depending on the type of anchor. These seismic demands were sometimes larger than those required by the reviewed code provisions for rigid NSC, but also for the most restrictive code-case for flexible NSC. The results presented different amounts of scatter, mostly related to the size of the annular gap and of the loading stiffness of the anchorage. It is shown that the maximum force achieved by the anchorage is directly related to the peak relative velocity of the NSC within the gap region. It was concluded that the shape of the shear hysteresis of the anchorage highly influences the response of the NSC and the anchor itself and should not be neglected in practice.

Metal flow hysteresis behavior and shape control strategy during porthole die extrusion of micro heat pipe

The shape control strategy of micro grooves is still unclear and challenging during the porthole die extrusion of grooved micro heat pipe (MHP). Through the simulation and experiment of porthole die extrusion of a MHP profile, the metal flow hysteresis behavior within micro features and the effect of ram speed and extrusion temperature on it and the resulting forming integrity was elucidated. Innovatively, Taguchi design and variance analysis (ANOVA) were introduced to determine their influence magnitude on the metal flow uniformity calculated by simulation results. The main findings are given below. The metal flow hysteresis derives from part feature size effect. The negligible friction-affected area during conventional extrusion severely slows down the metal flow within micro features during the MHP profile extrusion, which is due to the surge in the area ratio of the friction-affected area to the region in which it is located. Neither ram speed nor extrusion temperature can change the distribution of the friction-affected area. However, increasing ram speed multiplies the metal flow hysteresis and severely reduces the forming integrity, whereas extrusion temperature has little effect. Following this strategy, batch extrusion of the profile with micro-grooved width of 0.27 ± 0.02 mm was achieved in industrialized conditions.

Nitrate Hysteresis as a Tool for Revealing Storm‐Event Dynamics and Improving Water Quality Model Performance

AbstractUnderstanding the physics of nitrate contamination in surface and subsurface water is vital for mitigating downstream water quality impairment. Though high frequency sensor data have become readily available and computational models more accessible, the integration of these two methods for improved prediction is underdeveloped. The objective of this study was to utilize high‐frequency data to advance our understanding and model representation of nitrate transport for an agricultural karst spring in Kentucky, USA. We collected 2‐years of 15‐min nitrate and specific conductance data and analyzed source‐timing dynamics across dozens of events to develop a conceptual model for nitrate hysteresis in karst. Thereafter, we used the sensing data, specifically discharge‐concentration indices, to constrain modeled nitrate prediction bounds as well as the uncertainty of hydrologic and nitrogen processes, such as soil percolation and biogeochemical transformation. Observed nitrate hysteresis behavior at the spring was complex and included clockwise (n = 11), counterclockwise (n = 13), and figure‐eight (n = 10) shapes, which contrasts with surface systems that are often dominated by a single hysteresis shape. Sensing results highlight the importance of antecedent connectivity to nitrate‐rich storages in determining the timing of nitrate delivery to the spring. After integrating hysteresis analysis into our numerical model evaluation, simulated nitrate prediction bounds were reduced by 43 ± 12% and parameter uncertainty by 36 ± 20%. Taken together, this study suggests that discharge‐concentration indices derived from high‐frequency sensor data can be successfully integrated into numerical models to improve process representation and reduce modeled uncertainty.

Site selective response of cationic dopants in ZnO nanomaterials: Optical, dielectric and magnetic behaviors

Modulations of dielectric response and the investigation of magnetic property due to the percentage variation (3, 5 and 7 wt%) of chromium ion doping in 5 wt% yttrium doped-ZnO nanomaterials are considered in this report. The rods like Cr3+ and Y3+co-doped ZnO nanomaterials with polycrystalline single phase of wurtzite lattice structure are prepared by hydrothermal synthesis route. Frequency and temperature dependent dielectric response of all the co-doped ZnO nanomaterials were investigated in this report and the observation suggests that the dielectric permittivity of these co-doped ZnO nanomaterials can be modulated based on the site selectivity of the cationic dopants like Cr3+ or Y3+in between the lattice sites and the interstitial sites inside the host ZnO lattice structure. In addition, low temperature (10 K) magnetic ordering with ‘S’ shape hysteresis loop are observed. The hysteresis curve has been fitted and contribution of each magnetic phase (paramagnetic and ferromagnetic) has been extracted. This report is not only helpful to understand the modulation of dielectric response of ZnO like semiconducting materials depending on site selectivity of the cationic dopants inside the lattice structure of ZnO but also explore the underlying physics of DMS system consisting of multiple magnetic phases. This study shows that the semiconductors based dielectric materials are more effective for tailor made applications in various dielectric devices.

Thin Films of Solvatomagnetic CN‐Bridged Coordination Polymers: From Micro to Nanoscale

AbstractTwo types of thin films differing in thickness and morphology of microporous CN‐bridged hybrid organic–inorganic {[NiII(cyclam)]3[MIII(CN)6]2∙nH2O}n (M = Cr or Fe, cyclam = 1,4,7,11‐tetraazacyclotetradecane) coordination networks are obtained by using physical and chemical deposition techniques. By adsorption on the PET/ITO substrate of the pre‐formed nano‐sized crystallites from water suspension, films of 1–2 µm thickness composed of 40–200 nm size particles are obtained. The use of chemical sequential growth method, in which the coordination framework is anchored to the gold surface and built directly on the substrate from the cationic and anionic building blocks, reduces the film thickness to 100 nm and drastically improves film morphology. Both types of thin films show solvatomagnetic behavior characteristic for bulk compounds and change magnetic characteristics, including the shape of the magnetic hysteresis, under different humidity conditions.

Geomorphic control on stage-area hysteresis in three of the largest floodplain lakes

Hysteresis in floodplain lakes occurs between stage and lake area. Stage-area hysteresis controls the storage and exchange of water and sediments, and is a critical hydrological behavior for lake management. While hysteresis has been repeatedly observed in the floodplain lakes of large rivers, the hydrological mechanism and factors in control have been poorly understood thus far. In this paper, we investigate the role of geomorphology in controlling lake hysteresis, specifically the geologic setting and the lake basin, the lake position relative to the main stem of the river, as well as the influence of lake shape and its internal depositional landforms on inundation dynamics. We study the floodplain lakes along three of the largest rivers around the world: the Curuai Lake of the Amazon River, the Tonle Sap Lake of the Mekong River, and the Poyang Lake of the Yangtze River. The three lakes exhibit a similar counter-clockwise stage-area hysteresis: for a given stage, the lake area is larger in the falling season than in the rising season. Our results indicate that hysteresis is mainly controlled by geomorphology, where the lake shape and basin size lead to delays in the drainage and drop in lake area during the falling season, resulting in counter-clockwise hysteresis. Nevertheless, the lakes are of distinct climatic and geologic-geomorphic settings, representing the variety in the lake types of large rivers. Hence, while geomorphology is the overall driver, unique lake characteristics delay the fall in water extent and shape hysteresis on a case-by-case nature. At Curuai, the complex floodplain morphology (impeded floodplain) complicates and slows the routing of outflow. At Tonle Sap, the lake flows into the river solely through a narrow channel, where a backwater effect restricts drainage. At Poyang, the wide lake shape upstream leads to counter-clockwise hysteresis, while the narrow channel downstream exhibits clockwise hysteresis. Out of the three investigated floodplains, Tonle Sap has the largest degree of hysteresis (0.41), followed by Poyang (0.17) and Curuai (0.13). This trend in hysteresis extent is a result of the different composition of inflow and the lake–river hydrological connectivity, attributed to lake geomorphology. This study is the first to address geomorphology as the primary control over lake hysteresis, which improves understanding of the stage-area curve in empirical and numerical hydrological models, and potentially floodplain management.

Second-Harmonic Response in Magnetic Nodal-Line Semimetal Fe3GeTe2

We experimentally investigate second-harmonic transverse voltage response to ac electrical current for a magnetic nodal-line semimetal Fe3GeTe2 (FGT). For zero magnetic field, the observed second-harmonic voltage behaves as a square of the longitudinal current, as it should be expected for nonlinear Hall effect. The magnetic field behavior is found to be sophisticated: while the first-harmonic response shows the known anomalous Hall hysteresis in FGT, the second-harmonic Hall voltage is characterized by the pronounced high-field hysteresis and flat (B-independent) region with curves touching at low fields. The high-field hysteresis strongly depends on the magnetic field sweep rate, so it reflects some slow relaxation process. For the lowest rates, it is also accomplished by multiple crossing points. Similar shape of the second-harmonic hysteresis is known for skyrmion spin textures in nonlinear optics. Since skyrmions have been demonstrated for FGT by direct visualization techniques, we can connect the observed high-field relaxation with deformation of the skyrmion lattice. Thus, the second-harmonic Hall voltage response can be regarded as a tool to detect spin textures in transport experiments.

Micromagnetic and Microstructural Characterization of Ferromagnetic Steels in Different Heat Treatment Conditions

The paper addresses the investigation of microstructures from AISI 52100 and AISI 4140 in hardened as well as in quenched and tempered conditions. The specimens are compared in terms of their magnetic hysteresis and their microstructural and mechanical properties. Material properties were determined by hardness, microhardness, and X-ray diffraction measurements. Two different approaches were used to characterize magnetic properties via a hysteresis frame device, aiming, on the one hand, to record the magnetic hysteresis with established proceedings by setting a constant magnetic flux and, on the other hand, by offsetting a constant field strength to facilitate reproducibility of the results with other micromagnetic measurement systems. Comparable differences in both the micromagnetic and the mechanical material properties could be determined and quantified for the specifically manufactured specimens. The sensitivity of the magnetic hysteresis and, determined from that, the relationship between magnetic flux and magnetic field strength were confirmed. It was shown that a consistent change in hysteresis shape from hardened to high temperature tempered material states develops and that this change allows the characterization of different materials without the need to adjust magnetization parameters. Repeatedly, an increase in remanence with decreasing hardness was found for both test approaches. Likewise, a decreasing coercivity and increasing maximum magnetic flux could be detected with decreasing retained austenite content. The investigated correlations should thus contribute to the calibration of comparable measurement systems through the holistic characterized specimens.

Towards control of TiO2 thickness film in R-HiPIMS process with a coupled optical and electrical monitoring of plasma

In this work, optical emission spectroscopy and electrical measurements are implemented to investigate a reactive HiPIMS TiO2 deposition process running at duty cycles lower than 16% and at a repetition rate of 1 kHz. Investigations focus on both the effect of the discharge pulse duration and the reactive gas (O2) content in an Ar/O2 gas mixture at fixed working pressures. It is shown that a competition occurs between the pulse duration and the target poisoning, the latter being favored with short pulse duration although the mean power is kept constant. An unusual hysteresis shape observed between the two sputtering modes is also discussed. From combined analyses of Ti emission line intensity, discharge current and deposited TiO2 coating thickness, it is established that plasma diagnostics can be used effectively to control the deposition rate and to precisely manage the transition between metal and composite sputtering modes. Using these to calibrate a power feedback control loop could provide a better response compared to gas feedback control loop.

Tuning Hyrbrid Ferroelectric and Antiferroelectric Stacks for Low Power FeFET and FeRAM Applications by Using Laminated HSO and HZO films

AbstractThe properties of hybrid ferroelectric (FE) and antiFE (AFE) films integrated in a single capacitor stack is reported. The stack lamination (4 × 5 nm) or (2 × 10 nm) using an Alumina (Al2O3) interlayer, material type (Si‐doped HfO2 (HSO) and Zr doped HfO2 (HZO)), precursor condition (TEMA‐Hf and Hf/ZrCl4), or dopant concentration (Si and Zr) are investigated for laminate stack properties. Optimized FE properties (higher 2Pr and a lower fraction of the monoclinic phase) are observed at (2 × 10 nm) laminates compared to a single 20 nm film thickness. The hybrid laminate stack as FE‐FE, AFE‐FE, DE‐FE, or DE‐AFE using (2 × 10 nm) based laminates are explored in terms of the output FE hysteresis (2Pr, 2Ec) and structural properties by X‐ray diffraction. The hybrid AFE‐FE stack shows the potential of tailoring the output FE hysteresis 2Ec by varying the fraction of the AFE phase. The hybrid AFE‐FE stack is studied for the HSO and HZO materials at optimal FE content for the first laminate layer while varying the Si or Zr content to stabilize different degrees of an AFE phase in the second laminate layer. The superposition of the hybrid AFE‐FE hysteresis shows a systematic 2Ec control. A model is developed to describe the tailored output FE hysteresis via the tuning of a hybrid AFE‐FE stack. The role of stack lamination at hybrid‐stabilized phases inside a single stack is explored with the aim for a controlled and optimized FE hysteresis shape toward a low power (2Ec) operation.
