The orthorhombic rare-earth manganates and ferrites multiferroics are promising candidates for the next generation multistate spintronic devices. However, their ferroelectric polarization is small, transition temperature far below room (RT). improvement of ferroelectricity remains challenging. Here, through subtle strain defect engineering, an RT colossal 4.14 μC/cm 2 achieved in SmFeO 3−δ films, which two orders magnitude larger than its bulk also largest one among manganite ferrite family....
Owing to their wide application in oxide-based electrochemical and energy devices, ion conductors have attracted considerable attention. However, the ionic conductivity of developed systems is still too low satisfy low-temperature application. In this study, by developing emergent interphase strain engineering method, we achieve a colossal SrZrO3-xMgO nanocomposite films, which over one order magnitude higher than that currently widely used yttria-stabilized zirconia below 673 K....
Regulating the magnetic properties of multiferroics lays foundation for their prospective application in spintronic devices. Single-phase multiferroics, such as rare-earth ferrites, are promising candidates; however, they typically exhibit weak magnetism at room temperature (RT). Here, we significantly boosted RT ferromagnetism a representative ferrite, EuFeO3, by oxygen defect engineering. Polarized neutron reflectometry and magnetometry measurements reveal that saturation magnetization...
