Perovskite systems with structurally different multiferroic end members are being extensively investigated, because large phase-change magnetoelectric responses have been anticipated at the morphotropic phase boundaries (MPBs) between polymorphic forms differentiated ferroic orderings. (1-x) YMnO3-x BiFeO3 is one such system, for which two continuous perovskite solid solutions rhombohedral R3c ...
High saturation magnetization, perpendicular magnetic anisotropy, and high Curie temperature are required for ferromagnetic/ferroelectric thin films to apply the Race-Track memory, which next-generation recording devices. Therefore, in BiFeO3-based fi lms, amount of substituted La Bi A-site was xed at about 50 at%, Ni or Co Fe B-site varied from 0 35 respectively. The properties of（Bi,La）（Fe,Ni...
Ferroelectric random access memory is still challenging in the feature of combination of room temperature stability, non-destructive readout and high intensity storage. As a non-contact and non-destructive information readout method, surface potential has never been paid enough attention because of the unavoidable decay of the surface potential contrast between oppositely polarized domains. Tha...
Remarkably enhanced photovoltaic effects and first-principles calculations in neodymium doped BiFeO3
Remarkably enhanced photovoltaic effects have been observed in the heterostructures of p-type A-site Nd3+-doped BiFeO3 (Bi0.9375Nd0.0625)FeO3 (or BFONd) polycrystalline ceramics and the n-type ITO thin film. The maximum power conversion is ~0.82%, which is larger than 0.015% in BiFeO3 (BFO) under blue-ultraviolet irradiation of wavelength λ = 405 nm. The current-voltage (I-V) characteristic cur...
