Longitudinal Extension of Double π-Helix Enables Near-Infrared Amplified Dissymmetry and Chiroptical Response.

Near-infrared (NIR) circularly polarized light absorbing or emitting holds great promise for highly sensitive and precise bioimaging, biosensing, and photodetectors. Aiming at designing NIR chiral molecular systems with amplified dissymmetry and robust chiroptical response, herein, we present a series of double π-helical dimers with longitudinally extended π-entwined substructures via Ullmann or Yamamoto homocoupling reactions. Circular dichroism (CD) spectra revealed an approximate linear bathochromic shift with the rising number of naphthalene subunits, indicating a red to NIR chiroptical response. Particularly, the terrylene diimide-entwined dimers exhibited the strongest CD intensities, with the maximal |Δε| reaching up to 393 M-1 cm-1 at 666 nm for th-TDI[2]; and a record-high chiroptical response (|ΔΔε|) between the neutral and dianionic species of 520 M-1 cm-1 at 833 nm for th-TDI[2]Cl was achieved upon further reduction to its dianionic state. Time-dependent density functional theory (TDDFT) calculations suggested that the pronounced intensification of the CD spectra originated from a simultaneous enhancement of both electric (μ) and magnetic (m) transition dipole moments, ultimately leading to an overall increase in the rotatory strength (R). Notably, the circularly polarized luminescence (CPL) brightness (BCPL) reached 77 M-1 cm-1 for th-TDI[2]Cl, among the highest values reported for NIR-CPL emitters. Furthermore, all chiral dianions exhibited excellent air stability under ambient conditions with half-life times of up to 10 days in N-methylpyrrolidone (NMP), which is significant for future biological applications and chiroptic switches.

Exploring the supercapacitive potential of Sm3+ doped CoFe2O4 nanoparticles: Enhanced magnetic and dielectric properties

This study investigates the impact of Sm3+ substitution on the structural, electrical, magnetic, and electrochemical properties of CoFe2O4 nanoparticles prepared via a combined solid-state reaction and mechanical milling approach. Rietveld refinement analysis confirms the presence of single-phase cubic spinel structures within the Fd3m space group for both CoFe2O4 (CF) and Co0.95Sm0.05Fe2O4 (SmCF). Field emission scanning electron microscopy and energy dispersive spectroscopy are employed to validate the microstructure and elemental composition. Tauc plot analysis reveals a decrease in the band gap from 2.24 eV for CF to 2.07 eV for SmCF. Hysteresis loop measurements demonstrate an enhancement in saturation magnetization, remanent magnetization, and magnetic moment for SmCF, indicating improved magnetic properties. Furthermore, a substantial increase in magneto-crystalline anisotropy is observed with Sm³⁺ doping. Frequency-dependent dielectric properties are investigated using Havriliak–Negami fitting, confirming the presence of Cole-Cole dispersion. A direct correlation between the dielectric constant and temperature is identified, suggesting higher temperatures lead to elevated values. Notably, the incorporation of Sm³⁺ results in a significant enhancement in specific capacitance, positioning SmCF as a promising candidate for energy storage applications, particularly in supercapacitors.

Adjustment of ferromagnetism and improvement of the electronic structure of the TiI3 monolayer by the substitutional doping of 3d transition metal atoms: Ab-initio investigation

Two dimensional Van der Waals materials are very attractive for several researchers because of their distinctive properties and their interesting applications in data storage and spintronic devices. Titanium triiodide (TiI3), which is classified among transition metal trihalides (MX3), has received more attention after CrI3 and VI3 monolayers. Here, we explore the structural, electronic and magnetic properties of pure and 3d TM (TM = Sc, V, Cr, Mn and Fe) doped TiI3 monolayer using first-principles calculations, based on the GGA + Ueff approach. We confirmed the dynamic stability of TiI3 monolayer using phonon calculations and the thermal stability of pure and TM-doped TiI3 monolayers by performing AIMD simulation. We further found that the pure TiI3 monolayer is a stable ferromagnetic semiconductor with intrinsic magnetism. The introduction of vacancy defects in the pristine TiI3 monolayer showed that it is desirable to introduce TM atoms into Ti positions, which led to the improvement of its electronic and magnetic properties. The Sc-doped system keeps its semiconductor behavior with a reduction in the width of the band gap, whereas V-, Cr- and Fe-doped TiI3 monolayers turn into half semiconductors (HSC). Even more impressive, the Mn-doped system is found to be a bipolar ferromagnetic semiconductor (BFMS). We applied spin orbit coupling (SOC) on simulated monolayers, and showed that it affected them by changing their band gaps widths, especially in Fe-doped TiI3 monolayer. Furthermore, we found in all doped systems a ferromagnetic stability, an enhancement of the total magnetic moment, up to 10 μB in Cr- and Fe-doped monolayers, high Curie temperatures, up to 260 K, and high magnetic anisotropic energies, especially in Mn-doped TiI3 monolayer which makes it possess a long range ferromagnetic order. These interesting results concerning the electronic and magnetic properties of pure and transition metals-doped TiI3 monolayers are extremely beneficial for tune and enhance electronic and spintronic devices.

Electronic structure, magnetic and adsorption properties of monolayer chromium disulfide adsorbed by (non)-metals: A first-principles study

In this paper, the changes in the electronic structure, magnetic and adsorption properties induced by the adsorption of nine nonmetals (NMs) and twelve transition metals (TMs) on the monolayer CrS2 system have been investigated in the context based on the GGA+U methodology under the density-functional theory. The corresponding energetically most stable configurations were determined by calculating the formation energies for the four high-symmetry sites of each adsorption system. The atom adsorption induces a tunable electronic structure of the system, changing the surface structure and metallic properties of the monolayer CrS2. The system is made to show a wide variety of spintronic properties, such as narrow forbidden band semiconductors and semi-metals. Magnetically, the adsorbed atoms caused the redistribution of the electronic orbitals of the system, which formed local magnetic moments of different sizes at the adsorption sites and further caused the enhancement of the total magnetic moment of the system. The atom adsorption is expected to make monolayer CrS2 a potential spintronic material, which promotes the application of this material in nanoelectronics and spintronics.

Enhanced orbital magnetic moment of Co film grown on Fe3O4(001)

We investigate the magnetic and electronic properties of Co films on Fe3O4(001) achieved through epitaxial growth using magnetron sputtering. X-ray magnetic circularly dichroism measurements characterize the atomic magnetism. Compared to Co films on the MgO substrate, Co on Fe3O4 exhibits a 96% enhancement in orbital magnetic moment (from 0.25 to 0.49 µB/atom) and an increase in spin magnetic moment (from 1.37 to 1.53 µB/atom), resulting in an increased mratio(ml/ms) from 0.18 to 0.32. This enhancement of the orbital moment emerges as a consequence of the interface interaction between Co and Fe3O4. Density functional theory calculations attribute this heightened orbital magnetic moment to the robust electronic exchange interactions. Our findings not only offer insights into the modulation of magnetic and electronic characteristics in Co-based magnetic heterostructures but also provide valuable implications for the potential application of magnetic oxide/ferromagnetic heterostructures in future spintronic devices.

Origin of Enhancement of Orbital Magnetic Moment in SiO2-Coated Fe3O4 Nanocomposites Studied by X-ray Magnetic Circular Dichroism.

In this study, magnetic Fe3O4 nanoparticles (NPs) were dispersed uniformly by varying the thickness of the SiO2 coating, and their electronic and magnetic properties were investigated. X-ray diffraction confirmed the structural configuration of monophase inverse-spinel Fe3O4 NPs in nanometer size. Scanning electron microscopy revealed the formation of proper nonporous crystallite particles with a clear core-shell structure with silica on the surface of Fe3O4 NPs. The absorption mechanism studied through the zeta potential indicates that SiO2-coated Fe3O4 nanocomposites (SiO2@Fe3O4 NCs) possess electrostatic interactions to control their agglomeration in stabilizing suspensions by providing a protective shield of amorphous SiO2 on the oxide surface. High-resolution transmission electron microscopy images demonstrate a spherical morphology having an average grain diameter of ∼11-17 nm with increasing thickness of SiO2 coating with the addition of a quantitative presence and proportion of elements determined through elemental mapping and electron energy loss spectroscopy studies. Synchrotron-based element-specific soft X-ray absorption spectroscopy and X-ray magnetic circular dichroism (XMCD) techniques have been involved in the bulk-sensitive total fluorescence yield mode to understand the origin of magnetization in SiO2@Fe3O4 NCs. The magnetization hysteresis of Fe3O4 was determined by XMCD. At room temperature, the magnetic coercivity (Hc) is as high as 1 T, which is about 2 times more than the value of the thin film and about 5 times more pronounced than that of NPs. For noninteracting single-domain NPs with the Hc spread from 1 to 3 T, the Stoner-Wohlfarth model provided an intriguing explanation for the hysteresis curve. These curves determine the different components of Fe oxides present in the samples that derive the remnant magnetization involved in each oxidation state of Fe and clarify which Fe component is responsible for the resultant magnetism and magnetocrystalline anisotropy based on noninteracting single-domain particles.

Strain-tunable magnetic transition in few-layer 1T-VSe2

Two-dimensional vanadium diselenide (VSe2) has attracted extensive interest due to its room-temperature ferromagnetism with many potential applications. However, the intrinsic ferromagnetic (FM) ordering is confined to monolayers, which hinders their practical use because of fabrication difficulty. In this work, the effect of strain on magnetic properties of few-layer 1T-VSe2 is studied based on first-principles calculations. Spin-polarized density functional theory calculations indicate that the monolayer is intrinsic FM, while the bilayer, trilayer, and quadlayer 1T-VSe2 are intralayer FM but interlayer anti-ferromagnetic (AFM). The results predict that few-layer 1T-VSe2 can undergo a prominent magnetic transition from AFM to FM and an enhancement of magnetic moment by introducing in-plane tensile strain above 2%. A universal model is proposed to explain the enhanced FM that the structural deformation leads to symmetry breaking of the interlayer orbital hybridization, thus inducing FM of the whole system through an intralayer super-exchange effect. It is further verified on broader materials, including manganese and vanadium chalcogenides. This study provides a feasible route for achieving and modulating FM in two-dimensional materials, which have great significance in practical spintronic devices.

Tuning electronic properties and ferromagnetism of CrI3 monolayers with doped transition-metal atoms

Chromium triiodide (CrI3) monolayers have attracted much attention among the first two-dimensional materials discovered experimentally in both electronics and spintronics due to their potential applications. By means of density functional theory, we perform investigations of the electronic structures and magnetic properties of CrI3 monolayer doped with 3 d transition-metal (TM) atoms, which is also called CrXI6 monolayer with X changed from Sc to Fe. It is shown that the electron properties of the CrXI6 system can be tuned from semiconductor to metal/half-metal, which depend on the types of TM atoms. In addition, the CrXI6 system improves ferromagnetic (FM) stabilities, enhancement of magnetic moments, and FM-to-antiferromagnetic transition. These findings enrich the potential application perspectives of CrI3 monolayer in spintronics.

Electron Correlation Enhances Orbital Polarization at a Ferromagnetic Metal/Insulator Interface: Depth-Resolved X-ray Magnetic Circular Dichroism and First-Principles Study

The Fe(CoB)/MgO interface is vital to spintronics as it exhibits the tunneling magnetoresistance (TMR) effect and interfacial perpendicular magnetic anisotropy (PMA) simultaneously. To further enhance TMR and PMA for the development of high-density magnetoresistive random access memory, it is essential to clarify the behavior of Fe atoms interfaced with MgO. This study reveals that the spin and orbital magnetic moments of Fe are enhanced at the Fe/MgO interface. The enhancement in the orbital magnetic moment is much more significant than that predicted by the standard density functional theory. Theoretical calculations based on the orbital polarization correction reproduce this enhancement, the origin of which is attributed to the electron–electron correlation resulting from electron localization at the Fe/MgO interface. The present findings highlight the importance of electron–electron correlation at ferromagnet/oxide interfaces, which has often been disregarded in spintronics.

Magnetic moments of the octet, decuplet, low-lying charm, and low-lying bottom baryons in a nuclear medium

Abstract We study the magnetic moments of the octet, decuplet, low-lying charm, and low-lying bottom baryons with nonzero light quarks in symmetric nuclear matter using the quark–meson coupling (QMC) model, which satisfies the constraint for the allowed maximum change (swelling) of the in-medium nucleon size derived from the y-scaling data for 3He(e, e′) and 56Fe(e, e′). This is the first study to estimate the in-medium magnetic moments of the low-lying charm and bottom baryons with nonzero light quarks. The present QMC model also satisfies the expected allowed maximum enhancement of the nucleon magnetic moments in nuclear matter. Moreover, it has been proven that the calculated in-medium to free proton electromagnetic form factor (EMFF) ratios calculated within the QMC model reproduce well the proton EMFF super ratio extracted from $^4{\rm He}(\vec{e},e^{\prime }\vec{p})^3{\rm H}$ at Jefferson Laboratory. The medium modifications of the magnetic moments are estimated by evaluating the in-medium to free space baryon magnetic moment ratios to compensate the MIT bag deficiency to describe the free space octet baryon magnetic moments, where ratios are often measured directly in experiments even without knowing the absolute values, such as the free and bound proton electromagnetic form factors, as well as the European Muon Collaboration effect to extract the structure function F2 ratio of the bound to free nucleons by the corresponding cross section ratio. We also present the results calculated with the different current quark mass values for the strange and bottom quarks to see the possible impact. Furthermore, for practical use we give the explicit density-dependent parametrizations for the vector potentials of the baryons and light-(u, d) quarks, as well as for the effective masses of the baryons treated in this study, and of the mesons ω, ρ, K, K*, η, $\eta^{\prime}$, D, D*, B, and B*.

Structure and magnetism in metastable bcc Co[formula omitted]Mn[formula omitted] epitaxial films

Co-rich Co1−xMnx alloys have hcp or fcc disordered phase and those ferromagnetic orderings are significantly deteriorated with increasing Mn concentration x in bulk. On the other hand, those metastable bcc phases show properties attractive to magnetics and spintronics, as studied recently. Here, we report systematic study of structure and magnetism for epitaxial thin films. The single phase bcc Co1−xMnx(001) films were pseudomorphically grown on Cr(001) for 0.14<x<0.50 with a sputtering technique. The saturation magnetization was larger than that of pure Co for the films with x= 0.14 and 0.25 and smaller for the x= 0.34 films, disappearing completely for the x= 0.5 films. X-ray magnetic circular dichroism unveiled that this behavior stemmed from the composition dependence of elemental magnetic moments. Slight enhancement of magnetic moment of Co was observed in bcc alloy films. We also found that magnetic moments of Mn exceeded 2 μB at the maximum and were not as high as theoretical values, approximately 3 μB, obtained from ab-initio calculation with coherent potential approximation. This difference is qualitatively understood in terms of microscopic Mn atom pairing with antiferromagnetic coupling, being suggested from the ab-initio band structure calculations based on special quasi-random structure of bcc Co1−xMnx.

Defect Engineering: Electron-Exchange Integral Manipulation to Generate a Large Magnetocaloric Effect in Ni41Mn43Co6Sn10 Alloys.

A promising magnetocaloric effect has been obtained in Ni-(Co)-Mn-X (X = Sn, In, Sb)-based Heusler alloys, but the low isothermal magnetic entropy change ΔSM restricts the further promotion of such materials. Defect engineering is a useful method to modulate magnetic performance and shows great potential in improving the magnetocaloric effect. In this work, dense Ni vacancies are introduced in Ni41Mn43Co6Sn10 alloys by employing high-energy electron irradiation to adjust the magnetic properties. These vacancies bring about intense lattice distortion to change the distance between adjacent magnetic atoms, leading to a significant enhancement of the average magnetic moment. As a result, the saturation magnetization of ferromagnetic austenite is accordingly improved to generate a high isothermal magnetic entropy change ΔSM of 20.0 J/(kg K) at a very low magnetic field of ∼2 T.

Strain driven phase transition and mechanism for Fe/Ir(111) films

By way of introducing heterogeneous interfaces, the stabilization of crystallographic phases is critical to a viable strategy for developing materials with novel characteristics, such as occurrence of new structure phase, anomalous enhancement in magnetic moment, enhancement of efficiency as nanoportals. Because of the different lattice structures at the interface, heterogeneous interfaces serve as a platform for controlling pseudomorphic growth, nanostructure evolution and formation of strained clusters. However, our knowledge related to the strain accumulation phenomenon in ultrathin Fe layers on face-centered cubic (fcc) substrates remains limited. For Fe deposited on Ir(111), here we found the existence of strain accumulation at the interface and demonstrate a strain driven phase transition in which fcc-Fe is transformed to a bcc phase. By substituting the bulk modulus and the shear modulus and the experimental results of lattice parameters in cubic geometry, we obtain the strain energy density for different Fe thicknesses. A limited distortion mechanism is proposed for correlating the increasing interfacial strain energy, the surface energy, and a critical thickness. The calculation shows that the strained layers undergo a phase transition to the bulk structure above the critical thickness. The results are well consistent with experimental measurements. The strain driven phase transition and mechanism presented herein provide a fundamental understanding of strain accumulation at the bcc/fcc interface.

Enhancement of magnetic moment of Er-implanted ZnO films by post-annealing in Ar and vacuum

The Er ions have been introduced into ZnO films prepared by radio-frequency magnetic sputtering (RFMS) on sapphire substrates by ion implantation. The annealing effect on structural and magnetic properties for Er-implanted ZnO films under air, Ar, and vacuum atmospheres at 650 °C have been investigated systematically by a combined characterization of X-ray diffractions, Raman spectroscopy, Photoluminescence, X-ray photoelectron spectroscopy and Superconducting Quantum Interference Device. Strong room-temperature ferromagnetism has been observed for the as-implanted and annealed films. We found that the saturation magnetization varied greatly for different annealing conditions. A considerable enhancement in magnetization is observed for Er-doped ZnO annealed in vacuum, which is accompanied by an enhancement in the concentration of oxygen vacancy. Our results give clear evidence that the enhancement of ferromagnetism is strongly correlated with the increase of oxygen vacancies in Er-doped ZnO.

Magnetic Properties in CH3NH3PbI3 Perovskite Thin Films by Mn Doping

In recent years, perovskite halide compounds have attracted attention for the fabrication of highly efficient solar cells, light-emitting diodes, and X-ray detection. However, a comprehensive understanding of their microscopic origins has not been fully explored. In this work, the effect of Mn doping in organic–inorganic perovskite semiconductor methylammonium lead iodide (CH3NH3PbI3) has been studied. The existence of magnetism in CH3NH3PbI3 (MAPbI3) has been confirmed by magnetization measurements at room temperature. A drastic enhancement in magnetic moment is obtained in Mn (15%)-doped MAPbI3. The influence of Mn doping in MAPbI3 films has been analyzed for structural and morphological changes. Room-temperature ferromagnetism is achieved by the incorporation of Mn2+/Mn3+ ions into Mn (3–20%)-doped MAPbI3 films by the effect of eminent double-exchange and superexchange interactions in between the Mn2+–I––Mn3+ ions compared with other doping content. Our finding offers an alternative pathway for spintronic, light-controlled magnetic and photovoltaic devices.

Role of H-bond along with oxygen and zinc vacancies in the enhancement of ferromagnetic behavior of ZnO films: An experimental and first principle-based study

Magnetic properties of H2-ambience annealed pure ZnO films have been reported. ZnO films prepared by using DC magnetron sputtering show room temperature ferromagnetism (RT-FM) after annealing in hydrogen atmosphere at two different temperatures (350 °C and 400 °C). Enhancement in O-H concentration has been observed by analyzing core-level spectra recorded using x-ray photoelectron spectroscopy (XPS). The valence band spectra suggest the enhancement in carrier concentration after annealing in H2-ambience. Enhancement in the vacancy type defects have been observed by positron annihilation spectroscopy and tailoring of defects have been observed by photoluminescence spectra. Electrical transport results also indicate rapid decrease in activation energies corresponding to thermally activated band and nearest neighbor hopping (NNH) conduction, i.e. increase in carrier concentration after annealing. Increase in saturation magnetization and Zn vacancy (evident from M-H and PL data) along with the O-H concentration, after annealing in H2-ambience, suggest that Zn vacancies along with O-H concentration play a crucial role behind the ferromagnetic nature of the films. Surface morphology as examined by atomic force microscopy (AFM) shows that there is no significant variation of grain size and surface roughness of the films after annealing. The experimental results are further verified theoretically by performing the density functional theory calculations. Based on both experimental results and theoretical model, it has been explained that the enhancement of magnetic moment of H2-ambience annealed ZnO is because of the increased carrier mediated exchange interaction among the localized magnetic moment at VZn sites.

Large enhancement of magnetic moment in nitridated CeFe12

Due to success of desired doping, ion implantation has been widely used for semiconductor processing. In this work, we used nitrogen ion implantation to enhance magnetism in CeFe12 epitaxial thin films. To optimize nitrogen contents in CeFe12 and minimize the damage caused by the high-energy ion beam, we varied the thickness of the capping Mo layer. The saturation magnetization increased nearly 25% by nitrogen ion implantation into CeFe12 thin film. This phenomenon is explained by density functional theory calculations and confirmed by the magnetic resonance technique. The ion implantation and design strategy can be used for light-ion implantation into lattices to modulate magnetic, optical, and electrical properties.

Structural, electronic and magnetic properties of Co-substituted SrFe12O19: A DFT study

The electronic and magnetic properties of M-type strontium hexaferrite are investigated using first-principles density functional theory for both the pure state (SrFe12O19) and Co-substituted SrFe12O19 (Co0.5Sr0.5Fe12O19). The obtained substitution energy of Co0.5Sr0.5Fe12O19 proved the possibility of this substitution. The calculated densities of states (DOS) of pure SrFe12O19 hexaferrite showed a hard magnetic semiconductor behavior with a total magnetic moment of about 40.03 µB. Furthermore, a clear change of the magnetic behavior is observed while substituting SrFe12O19 with Cobalt element, where a polarization at Fermi level is obtained, which characterize the half-metallic materials with an enhancement of the total magnetic moment. Our obtained results could pave the way to further experimental and theoretical investigations on the spintronic applications of M-type strontium hexaferrite.

Electronic and crystal structures of LnFeAsO1−x H x (Ln = La, Sm) studied by x-ray absorption spectroscopy, x-ray emission spectroscopy, and x-ray diffraction (part I: carrier-doping dependence)

A carrier doping by a hydrogen substitution in LaFeAsO1−x H x is known to cause two superconducting (SC) domes with the magnetic order at both end sides of the doping. In contrast, SmFeAsO1−x H x has a similar phase diagram but shows single SC dome. Here, we investigated the electronic and crystal structures for iron oxynitride LnFeAsO1−x H x (Ln = La, Sm) with the range of x = 0–0.5 by using x-ray absorption spectroscopy, x-ray emission spectroscopy, and x-ray diffraction. For both compounds, we observed that the pre-edge peaks of x-ray absorption spectra near the Fe-K edge were reduced in intensity on doping. The character arises from the weaker As–Fe hybridization with the longer As–Fe distance in the higher doped region. We can reproduce the spectra near the Fe-K edge according to the Anderson impurity model with realistic valence structures using the local-density approximation (LDA) plus dynamical mean-field theory (DMFT). For Ln = Sm, the integrated-absolute difference (IAD) analysis from x-ray Fe-Kβ emission spectra increases significantly. This is attributed to the enhancement of magnetic moment of Fe 3d electrons stemming from the localized picture in the higher doped region. A theoretical simulation implementing the self-consistent vertex-correction method reveals that the single dome superconducting phase for Ln = Sm arises from a better nesting condition in comparison with Ln = La.

Optical nonlinear, EPR, second harmonic generation and Faraday rotation studies on diamagnetic solid: Influence of thermal poling

The electric field manipulation of magnetic and magneto optical properties is currently of great interest for photonics and spintronics devices. In this study, for the first time, we utilized the thermal poling electric field induced polarization and magnetization to manipulate the magnetic and Faraday rotation performance of heavy metal oxide diamagnetic glass. The influence of poling conditions on second & third nonlinearity, structure and defects, thermal, magnetic and magneto optical properties were studied through varies characterization techniques such as scanning electron microscope, X-ray powder diffraction, Raman, maker fringe, electron paramagnetic resonance, X-ray photoelectron spectroscopy, Z-scan, vibration sample magnetometer and Faraday rotation measurements. 5 µm-thickness layer second harmonic generation intensity increased with the voltages from 1 kV to 3 kV, while at 300°C second harmonic generation the intensity decreased. Third nonlinearity coefficient and nonlinear refractive index were calculated to be much higher than that of un-poled glass through the Z-scan method. X-ray photoelectron spectroscopy, Raman and electron paramagnetic resonance analysis revealed the center-asymmetric network of glass, non-bridging oxygen and defect centers after thermal poling. The modification on glass structure resulted in the enhancement of magnetic moment of glass with electric induced magnetic field changes electric coupling effect as high as 15%. Faraday rotation measurement indicated that polarization dominantly contributed to the enhancement of V, at the same time, the V also was impacted by glass transmittance and crystal scattering. The optimized thermal poling condition was determined to be 3 kVand 260°C for 4 hours, under which thermally poled glass presented the strong second harmonic generation intensity (2.3 pm/V), highest Verdet constant (0.2382 min/G.cm) and improved diamagnetic susceptibility (0.424×10−5 emu/mol). Diamagnetic glass with these properties is attractive for magneto optical sensing and nonlinear applications.
