Dielectric, electrochemical and magnetic properties of the hydrothermally synthesized double perovskite La2NiMnO6 for energy storage applications

Double perovskite materials are greatly appealing because of their multiferroic properties. Among such materials, double perovskite with rare earth metals are widely studied by researchers. Presently, the double perovskite La2NiMnO6 (LNMO) samples are synthesized using the hydrothermal method by varying the concentration of the solvent (NaOH). The Powder X-ray diffraction analysis confirmed the formation of monoclinic structure with the P21/n space group for prepared LNMO samples. The SEM image of the prepared samples revealed a cube-like structure. The impedance, dielectric, AC conductivity and modulus are studied in a wide frequency range from 100 Hz to 5 MHz to analyse the electrical and microstructure properties of the synthesized LNMO samples. The presence of a non- Debye type of relaxation peak is confirmed by impedance, dielectric and modulus studies. The effect of grains and grain boundaries are analysed by the Nyquist plot and the polarization of the materials are explained by the Maxwell-Wagner interfacial polarization model and Koop's theory. Using a three electrode system, the electrochemical behaviour of prepared LNMO samples are studied in various concentration of electrolyte (KOH) at different scan rates and found to have a pseudocapacitive nature. The highest specific capacitance value for LNMO10 is 44.60 F/g, LNMO20 is 50.14 F/g and LNMO30 is 25.81 F/g at a scan rate of 10 mV/s for 3 M KOH. The room temperature magnetic behaviour of synthesized LNMO samples analysed by Vibrating Sample Magnetometer paves way for magnetic storage applications.

Origin of Multiferroism of Ion Doped at Different Sites: Bi4Ti3O12 Bulk and Nanoparticles

Based on a microscopic model and the Green's function theory, the temperature, size, magnetic field, and ion doping dependence of the magnetic, electric, and dielectric properties in Fe‐and Nd‐doped ferroelectric Bi4Ti3O12 bulk and nanoparticles is investigated. The multiferroism can be achieved in two ways. At once the magnetism appears by substitution of the nonmagnetic Ti ion with Fe or other transition metal ions in bulk Bi4Ti3O12. Otherwise, the simultaneous existence of Fe and Fe gives rise to a superexchange mechanism responsible for ferromagnetic interaction. Moreover, multiferroism is possible also in pure Bi4Ti3O12 nanoparticles. Due to surface effects and oxygen vacancies leading to different valence states on the surface of Ti or Ti with spin value , there appears weak magnetism, which can be improved by Fe ion doping. It is demonstrated that doping with rare earth ions, for example Nd, at the Bi site is able to improve the ferroelectric, multiferroic, and dielectric properties.

Magnetic and Ferroelectric Manipulation of Valley Physics in Janus Piezoelectric Materials.

The realization of multiferroic materials offers the possibility of multifunctional electronic device design. However, the coupling between the multiferroicity and piezoelectricity in Janus materials is rarely reported. In this study, we propose a mechanism for manipulating valley physics by magnetization reversing and ferroelectric switching in multiferroic and piezoelectric material. The ferromagnetic VSiGeP4 monolayer exhibits a large valley polarization up to 100 meV, which can be effectively operated by reversing magnetization. Interestingly, the antiferromagnetic VSiGeP4 bilayers with AB and BA stacking configurations allow the coexistence of valley polarization and ferroelectricity, supporting the proposed strategy for manipulating valley physics via ferroelectric switching and interlayer sliding. In addition, the VSiGeP4 monolayer contains remarkable tunable piezoelectricity regulated by electron correlation U. This study proposes a feasible idea for regulating valley polarization and a general design idea for multifunctional devices with multiferroic and piezoelectric properties, facilitating the miniaturization and integration of nanodevices.

Synthesis and Characterization of Cr-Doped Pb2Fe2O5 Thin Films by Reactive Magnetron Sputtering

Multiferroic materials, which exhibit simultaneous ferroelectricity, ferromagnetism, and ferro-elasticity, have attracted significant attention due to their multifunctional properties. Coupling between ferroelectric and magnetic properties has led to the development of non-volatile memory devices, transducers, magnetic field sensors, and other applications. Pb2Fe2O5 (PFO) is a promising multiferroic material due to it simultaneously exhibiting ferroelectricity and ferromagnetism at room temperature. Doping with aliovalent ions, such as Cr3+, has been proposed as an effective method for enhancing the ferroelectric and magnetic properties, consequently leading to the enhancement of multiferroic properties. The investigation shows that the lead ferrite phase (220) was present in all samples, but its abundance reduced with increasing synthesis temperature due to lead desorption. Dielectric measurements revealed that PFO films with highest Cr concentration had the highest polarization (Pr) of 72.2 μC cm−2. The study also found that the magnetization of PFO films was up to 9.5·10−7 μAm2 at an ambient temperature of 5 K, and the magnetic ordering temperature was 363 K, corresponding to the magnetic ordering temperature of chromium oxides. The morphology of Cr doped PFO films changed with increasing chromium content, resulting in a reduction in grain size and an increase in the film density.

Rare Earth Nitrate Hybrid Double Perovskites [Me4N]2[MLn(NO3)6] (M = Na-Cs; Ln = La-Gd, ex. Pm).

An exploration of the synthetic and structural phase space of rare earth hybrid double perovskites A2B'BX6 (A = organocation, B' = M+, B = M3+, X = molecular bridging anion) that include X = NO3- and B' = alkali metal is reported, complementing earlier studies of the [Me4N]2[KB(NO3)6] (B = Am, Cm, La-Nd, Sm-Lu, Y) (Me4N = (CH3)4N+) compounds. In the present efforts, the synthetic phase space of these systems is explored by varying the identity of the alkali metal ion at the B'-site. Herein, we report three new series of the form [Me4N]2[B'B(NO3)6] (B = La-Nd, Sm-Gd; B' = Na, Rb, Cs). The early members of the Na-series crystallize in the trigonal space group R3̅ from La to Nd where a phase transition occurs in the phase between 273 and 300 K, going from R3̅ to the high-symmetry, cubic space group Fm3̅m. The preceding trigonal members of the Na-series also undergo phase transitions to cubic symmetry at temperatures above 300 K, establishing a decreasing trend in the phase-transition temperature. The remainder of the Na-series, as well as the Rb- and Cs-series, all crystallize in Fm3̅m at 300 K. The temperature-dependent phase behavior of the synthesized phases is studied via variable-temperature spectroscopic methods and high-resolution powder X-ray diffractometry. All phases were characterized via single-crystal and powder X-ray diffraction and Fourier transform infrared (FT-IR) and Raman spectroscopic methods. These results demonstrate the versatility of the perovskite structure type to include rare earth ions, nitrate ions, and a suite of alkali metal ions and serve as a foundation for the design of functional rare earth hybrid double perovskite materials such as those possessing useful multiferroic, optical, and magnetic properties.

Extraordinary role of Nd3+ doping on high temperature stable multiferroic and magneto electric properties of Bi1-xNdxFeO3-Bi2Fe4O9/Sr1-xCaxTiO3 dual phase ceramic composite

The Bi1-xNdxFeO3-Bi2Fe4O9/Sr1-xCaxTiO3 (BNFO-SCT) ceramic material displays multiferroic properties after being synthesized via using both the traditional solid-state method and the mechanical alloying technique. Nd3+ was added to the BNFO-SCT as a dopant, and the effects on the microstructure, dielectric characteristics, ferroelectric properties, and piezoelectric properties were examined using a variety of analytical techniques. With addition of Nd3+ dopants in BNFO-SCT, a two-phase structure that changed from rhombohedral perovskite (R3c) to triclinic (P1) and a significant increase in dielectric properties were observed. The remnant polarization, coercive electric field, and magnetocapacitance coefficient showed notable enhancement with increasing Nd3+ doping (x) up to 0.6, thereafter, all these properties began to decrease. Moreover, the leakage current of the BNFO-SCT material decreased with higher Nd3+ content. Interestingly, the dielectric properties at room temperature exhibited a substantial increase when subjected to an applied magnetic field.

Structural phase transitions, mechanical properties, and electronic band structures of room-temperature ferromagnetic monolayers ScMP2 (M = Mn and Cr)

Two-dimensional (2D) auxetic properties and ferromagnetism are two major focuses of research for next-generation nanomechanical and spintronic devices. However, 2D materials with the two properties at the same time are rarely reported. Based on first-principles calculations, we propose the 2D bimetallic phosphide ScMP2 (M = Mn and Cr), including three stable tetragonal monolayers. The monolayer ScMnP2 exhibit the square structural phase while there is a structural phase transition between the square ScCrP2 and the rectangular ScCrP2, which originates from the mechanism of ferroelasticity and ferroelectricity. Both monolayers ScCrP2 exhibit in-plane auxetic properties, and the value of the negative Poisson’s ratio can reach –0.322. All the three monolayers show a ferromagnetic ground state with high Curie temperature, and are a Dirac half-metal without spin–orbit coupling (SOC). When considering SOC, a nontrivial bandgap can be found in the monolayer ScMnP2, which further becomes a half-Chern insulator. Importantly, the structural phase transitions from the square lattice to the rectangular lattice in the monolayers ScCrP2 will enable a significant improvement in the values of negative Poisson’s ratio and magnetic anisotropic energy simultaneously. Taking the multiferroic (ferroelastic, ferroelectric, and ferromagnetic), auxetic, and topological properties into consideration, the 2D system of ScMP2 provide promising applications for future multifunctional nanodevices.

Multiferroic properties of BiFeO3 thin films with Ce substitution

In this study, we investigated the crystalline structure, ferroelectricity, leakage current density, magnetic, and nanomechanical properties of BiFeO3 (BFO) films with Ce substitution. Bi1-xCexFeO3 (BCFO) films with x = 0.00, 0.03, 0.06, 0.09, and 0.15 were deposited on glass substrates by using pulsed laser deposition. The experimental results showed that the BCFO films mainly composed the perovskite phase. The structure changed from rhombohedral when x = 0.00 to pseudo-cubic when x = 0.03, and pseudo-cubic phase coexisted with an additional Bi2Fe4O9 phase when x = 0.06–0.09. The BCFO films exhibited improved ferroelectricity and desirable magnetic characteristics. The remanent polarization (2Pr) increased significantly with the Ce concentration, reaching 189.3 μC/cm2 and 100.0 μC/cm2 when x = 0.03 and x = 0.06, respectively, but decreasing at higher Ce contents. The BCFO film with x = 0.03 had a remarkable 2Pr value of 189 μC/cm2 after 108 cycles due to the high (110) texture, fine microstructure, and flat interface resulting in strong anti-fatigue properties. The leakage mechanisms in the BCFO films were also examined. The films exhibited enhanced saturation magnetization (Ms) values ranging from 3.8 to 10.0 emu/cm3, which were attributed to suppression of the spiral spin configuration and the larger magnetic moment associated with the Ce3+ ion. The nanomechanical characteristics of the BCFO films, such as hardness, were significantly influenced by the grain size and phase composition. These findings provide valuable insights into enhancement of the multiferroic properties of BFO polycrystalline films through Ce substitution for use in various applications.

Investigation on the effect of magnetostriction on the magnetoelectric coupling of BaTiO3 - Ni(1-x) Zn(x) Fe2O4 multiferroic particulate composites

BaTiO3-Ni(1-x)Zn(x)Fe2O4(x = 0,0.5,1)multiferroic composites with varying magnetic phases are prepared by combined sol-gel and polyol method. The physical and chemical properties of the systems are studied. The detailed analysis on the role of magnetostriction in magnetoelectric coupling is carried out by varying the dopant in magnetic phase. The coexistence of two phases of nanosized structure, without any impurities is confirmed from XRD Rietveld refinement. The mixed composite nature, well-defined connectivity between two phases and the crystallinity are well established from the HRTEM - SAED analysis. The multiferroic property of composites are verified by analysing the ferroelectric P-E loop and magnetic M−H loop. The ferromagnetic and antiferromagnetic nature of BaTiO3-Ni(1-x)Zn(x)Fe2O4is due to the mixedand normal spinel structure of the magnetostrictive phases in the composite. The BaTiO3-Ni0.5Zn0.5Fe2O4composite exhibited enhanced magnetoelectric coupling due to the large magnetostrictive strain induced by the Ni0.5Zn0.5Fe2O4on BaTiO3.

Structural, Spectroscopic, and Electrical Properties of (Ho, Mn)‐Codoped Bismuth Ferrites Synthesized Through Solid‐State Route

Bismuth ferrites (BiFeO3) are popularly known as BFOs and have potential application at room temperature in present‐day material science and ceramic industry due to their multiferroic and optical properties. Synthesis methods, temperature treatments, and doping are effective for tuning the structural and multiferroic properties of BFO, among which rare earth metals in Bi‐site and transition metals in Fe‐site have shown interesting results. This work explores the synthesis and characterizations of (holmium, manganese)‐codoped BFOs where solid‐state synthesis route and some electrical analyses are the novel studies attempted herein. X‐ray diffraction results explain the structural transition from rhombohedral to mixed‐phase ordering. Grain formation and the elemental concentrations are studied using scanning electron microscopy (SEM) and energy‐dispersive ray spectra (EDAX). Electrical analysis such as dielectric behavior with respect to frequency and temperature impedance analysis is studied in detail. Polarization versus electric field (P–E) hysteresis loop shows the ferroelectric nature of the codoped sample with lossy nature and reduced remnant polarization with doping. The dielectric anomalies with frequency and temperature are analyzed in detail, and antiferromagnetic transition around Neel temperature is discussed.

Energy storage and multiferroic properties of La-doped epitaxial BiFeO3 thin films according to La doping concentration

La-doped epitaxial BiFeO3 (LBFO) thin films with La doping concentrations of 0, 10, 20, 25, and 30 % were deposited by pulsed laser deposition on Nb-doped single-crystal SrTiO3 substrates. The LBFO thin films doped with a La doping concentration of 10 % showed the best ferroelectric properties due to a large c/a ratio of about 1.04. As the concentration of La increased, the ferroelectric polarizations of the LBFO films decreased while the ferromagnetic properties steadily improved. In particular, the LBFO thin films tended to increase energy storage efficiency as the concentration of La increased, and the LBFO thin films with a La doping concentration of 30 % showed a high energy storage density of about 30.7 J/cm3.

Investigating the structure, magnetism, magnetocaloric effects and critical behavior of Eu(Ti,B)O3 perovskites

EuTiO3 exhibits various interesting physical properties, including magnetocaloric effect, quantum paraelectricity, magnetoelectricity, and multiferroic properties, thus attracting a broad range of attention from the researchers. The delicate balance between ferromagnetic coupling and antiferromagnetic interactions offers the feasibility of modulating the magnetic properties and magnetocaloric effect for this perovskite. Herein, a range of Eu(Ti,B)O3 perovskites were prepared by substituting titanium with different amounts of boron. A comprehensive investigation on their structure, magnetism, magnetocaloric effect, and critical behavior was performed. All the compounds are confirmed to be crystallized in a single cubic perovskite structure with space symmetry of Pm3m, with the introduced boron uniformly distributed in the compounds. The transition temperatures are determined to be 6.0, 6.5, 5.0, and 5.0 K for EuTi0.9375B0.0625O3, EuTi0.875B0.125O3, EuTi0.8125B0.1875O3, and EuTi0.75B0.25O3, respectively. The results of both magnetic measurements and critical behavior analysis suggest that appropriate substitution of boron promotes the magnetic transition from AFM to FM in Eu(Ti,B)O3. In addition, significantly enhanced low-field magnetocaloric effects were observed in these perovskites. Under field changes of 0–1 and 0–2 T, the values of -ΔSMmax are 14.7 and 26.4 J·kg−1·K−1 for EuTi0.8125B0.1875O3, 15.2 and 27.4 J·kg−1·K−1 for EuTi0.75B0.25O3, respectively.

Superior energy storage performance and excellent multiferroic properties of BaTi1-xGdxO3 (0 ≤ x ≤ 0.06) ceramics

Ceramic based capacitors with superior energy storage performance and high storage energy density play an important role in modern electronic devices. Several ferroelectric materials with high dielectric constant and relaxor behavior become the most promising systems for realizing higher energy storage performance. In the present work, environmentally lead-free BaTi1-xGdxO3 (0 ≤ x ≤ 0.06) nanostructures were synthesized using the sol-gel auto-combustion process. The doping of Gd at the Ti site causes the transformation of the ferroelectric behavior to the relaxor ceramics, which is important for finding the large energy storage efficiency of the material. The surface morphology of undoped and doped samples was examined through the SEM studies. Ferroelectric study evidence that the system is going to a more symmetric phase due to a reduction in the polarization parameters and enhancement in the leakage current density. Moreover, the energy discharge density and energy storage efficiency were boosted in x = 0.02 and x = 0.04 samples with energy storage efficiencies reaching ∼81% and 83%, respectively. The linear enhancement in the magnetic moment and the dielectric constant in the doped sample make the system favorable for multifunctional applications. The samples' piezoelectric constant (d33) remains preserved under Gd doping. Hence, the present study opens a propagable and feasible route to synthesize novel lead-free ferroelectric material for energy storage applications.

Nanoscale Size Effects on Push-Pull Fe-O Hybridization through the Multiferroic Transition of Perovskite ϵ-Fe2O3.

Multiferroics have tremendous potential to revolutionize logic and memory devices through new functionalities and energy efficiencies. To reach their optimal capabilities will require better understanding and enhancement of the ferroic orders and couplings. Herein, we use ϵ-Fe2O3 as a model system with a simplifying single magnetic ion. Using 15, 20, and 30 nm nanoparticles, we identify that a modified and size-dependent Fe-O hybridization changes the spin-orbit coupling and strengthens it via longer octahedra chains. Fe-O hybridization is modified through the incommensurate phase, with a unique two-step rearrangement of the electronic environment through this transition with attraction and then repulsion of electrons around tetrahedral Fe. Interestingly, size effects disappear in the high-temperature phase where the strongest Fe-O hybridization occurs. By manipulating this hybridization, we tune and control the multiferroic properties.

Ferroelectric and negative piezoelectric properties in oxyhydroxide monolayers γ -XOOH (X = Al, Ga, and In)

Two-dimensional (2D) multiferroic materials with coexisting ferroelasticity (FA) and ferroelectricity (FE) have potential applications in high-density data storage and sonar detectors. Here, based on first-principles calculations, we predict a series of stable 2D FA-FE multiferroic structures, namely, γ-XOOH (X = Al, Ga, and In) monolayers. By analyzing the lattice symmetry and orientation distribution of hydroxyls, we find that XOOH monolayers possess both in-plane ferroelastic and ferroelectric polarization, as well as antiferroelectric ordering caused by the anti-parallel alignment of hydroxyls. Interestingly, the perpendicular reorientation of in-plane FE polarization accompanies 90° ferroelastic switching. Moreover, they show an unusual negative transverse piezoelectric effect originated from the clamped-ion term. The multiferroic properties of the XOOH monolayers provide an excellent platform to study electroelastic effects.

Role of 5 mol% rare earth (La3+) on the structural, microstructural, and magnetic properties of cobalt chromite ceramics

Spinel oxides, which have the structure AB2O4 and are distinguished by their exceptional magnetic, electric, and multiferroic properties and exhibit a wide range of functional responses in the category of oxides. The cobalt chromate (CoCr2O4) is well-known as a multiferroic-magnetoelctric (ME) material. It belongs to the magnetic spinal oxide family and is noted for its complicated spiral ferromagnetic(FM) orderings. To enhance the magnetic properties of the CoCr2O4, in this work we have chosen Lanthanum (La3+) 0.05 mol% doped cobalt chromites (CoCr2O4) nanoparticles. The solution combustion method was utilized to synthesize the nanomaterial, where urea and glucose were used as fuels. The Structural exploration of the Co0.95La0.05 Cr2O4 nanoparticles were clarified using powder X-ray diffraction. To understand the microstructure properties we have carried out high-resolution electron microscopy and it reveals highly porous nature. In FTIR spectra the two main absorption bands at 507 cm−1 and 616 cm−1 were observed which confirm the formation of spinal chromates. The TGA results revealed a slow thermal degradation, and the sample has a thermal stability that is greater than the temperature range tested. Researchers have examined the changes in temperature and magnetic field affected the magnetic properties of materials over time (ZFC & FC). In comparison to the bulk sample, the Curie temperature at which samples transition from a paramagnetic (PM) state to a collinear short-range ferromagnetic (FM) state is significantly lower. This temperature is denoted as TC-98 K deteriorated with time in terms of quality. At low temperatures, there is no magnetic transition that can be identified between the short-range FM order and the long-range spiral spin structure. This is in contrast to the magnetic transitions that can be discovered in bulk. What gives rise to all of the intriguing qualities that have been described above is the presence of weak magnetic frustration, which is very much connected to super-exchange interactions and is found along different paths such as A-O-A, B–O–B, and A-O-B. This presence is what gives rise to all of the intriguing characteristics that have been described above.

Perspectives on MXene-PZT based ferroelectric memristor in computation in memory applications

Lead zirconate titanate (PZT) is the promising candidate in advanced ferroelectric memory application due to its excellent piezoelectricity, ferroelectricity, pyroelectricity, non-linear dielectric behavior, multiferroic properties, high ferroelectric Curie temperature, and extremely strong stability. It has gained attention in the field beyond von-Neumann computing, which inspires the development of computation in memory applications. Various structures of the ferroelectric memristive device, including ferroelectric field effect transistor, tunnel junctions, nonvolatile memory, and capacitor, based on PZT have been proposed for the realization of computation in memory application. On the other hand, unique designs realize the performance enhancement of PZT ferroelectric memristive devices, i.e., the insertion of 2D material MXene. This perspective further points out some of the challenges that MXene-PZT based ferroelectric memristive devices encounter in reality and finally give our viewpoint on possible developments toward computation in memory in a neuromorphic platform.

Insights into the correlation between ionic characteristics and microstructure and multiferroic properties in KNN-based ceramics with BiMO3 modification

As one of the most promising eco-friendly piezoelectric materials, potassium sodium niobate (KNN)-based ceramics prepared via a phase engineering strategy have recently received considerable attention. Surprisingly, the different piezoelectric properties can also be obtained in KNN-based ceramics even with the same phase coexistence, illustrating that the mechanisms of improved properties have not been sufficiently addressed apart from phase coexistence, especially the role of the characteristics of individual elements in the modification of structure and performance. Herein, a group of BiMO3-doped KNN-based ceramics was designed to probe the qualitative correlation between ionic characteristics (ionic radius and electronegativity) and structure as well as multiferroic properties. Due to the different efficiency of ion on shifting phase transition temperatures, the R-T phase boundary with varying R and T phase fractions is displayed in BM ceramics, while the evolution of relaxor behaviour is ascribed to the decreased grain size resulting from the enhanced ionic radii of Ga3+, Fe3+, and Sc3+. Owing to the distinction in the covalence fraction caused by the electronegativity, d33 first increased and then decreased from BG to BF to BS ceramics. The superimposed effect of the T-phase fraction, c/a ratio, and covalence fraction dominates the evolution of the temperature-dependent normalised electric properties. Additionally, higher magnetic properties are beneficial for the super-exchange interactions occurring with the –Fe–O–Nb–O–Fe– pathways in BF ceramics. Therefore, exploring the role of characteristics for individual elements in the structure and performance is helpful for sufficiently understand the doping mechanism.

Effect of sintering temperature on structural, electrical, and magnetic properties of Bi2Fe4O9 polycrystalline materials

In the present paper, the effect of sintering temperatures (500 0C to 800 0C) on structural, and multiferroic properties of double perovskite Bismuth Ferrite (Bi2Fe4O9) materials synthesized through co-precipitation method has been investigated. The Powder X-ray diffraction and Raman spectroscopic studies revealed the formation of Mullite type Bismuth Ferrite (Bi2Fe4O9) with orthorhombic (Pbam) structure. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) investigations reveal the formation of cuboid shape nanoparticles closely packed to each other. The particle size increases with increasing the sintering temperature from 500 0C to 800 0C. The Transmission electron microscopic (TEM) technique employed in both imaging and diffraction modes also confirms the growth of cubic nanocrystals of Bismuth Ferrite (Bi2Fe4O9). The saturated polarization–field curves for all samples sintered at different temperatures indicate the improvement of ferroelectric properties. The magnetic properties of Bi2Fe4O9 were investigated through hysteresis loops. The unsaturated curve of the magnetic field-dependent magnetization (M−H) of the materials at room temperature exhibits anti-ferromagnetic behavior.

Magnetoelectric multiferroic properties of BaTiO3-CoFe2O4-BaTiO3 tri-layer thin films fabricated by pulsed laser deposition

A magnetoelectric multiferroic bi-phase system with robust ferroelectric and ferro/ferri-magnetism response at room temperature would be ideally suitable for microelectronics, memory devices, and for spintronic applications. BaTiO3/CoFe2O4/BaTiO3(BTO/CFO/BTO) heterostructured films were pulsed laser deposition grown on Pt(111)/TiO2/SiO2/Si substrates. High quality polycrystalline films were grown by thermal annealing at 750 °C, at an oxygen partial pressure of 100 mTorr for 1 h. Crystal quality and phase formation information was monitored using X-ray diffraction (XRD). XRD confirm the growth of polycrystalline heterostructures and the coexistence of both perovskite BTO and spinel CFO phases in heterostructures. In order to obtain robust magnetoelectric coupling, we studied the tri-layer structure as a representative ferroelectric/ferrimagnetic/ferroelectric system. We report the ferroelectric, leakage current behavior, ferrimagnetic, and frequency dependent ME properties of the films. Ferroelectric BTO and ferrimagnetic inverse spinel CFO nature is also confirmed using the piezoresponse force microscopy and magnetic force microscopy measurements. These nanostructures exhibit high saturation polarization (Ps ∼ 99.86 µC/cm2), saturation magnetization (Ms ∼ 51.48 emu/cm3), and a strong ME coupling coefficient of ∼ 274 mV/cm-Oe with a bias magnetic field of + 90 Oe, anda frequency of 1 kHz revealing them as prospective candidates for multifunctional applications.
