Enhancement of polarization and magnetization in polycrystalline magnetoelectric composite
arXiv:2103.13738 · doi:10.1063/5.0085323
Abstract
Electrical control of magnetization or magnetic control of polarization offers an extra degree of freedom in materials possessing both electric and magnetic dipole moments viz., magnetoelectric multiferroics. Microstructure with polycrystalline configurations that enhances the overall polarization/magnetization and that outperform single crystalline configurations are identified. The characterization of local fields corresponding to the polycrystal configuration underlines nontrivial role played by randomness in better cross-coupling mediated by anisotropic and asymmetric strains.
