Abstract

Using pure electric voltages instead of magnetic fields or large currents to manipulate magnetisms in multiferroic heterostructures is a goal for future low-power spintronics such as electric-writing magnetic-reading memories. Usually, the electric manipulation to magnetism shows a volatile effect which cannot be used for information storage,[1] because the magnetic variation vanishes after the electric field removal. Recently, the piezostrain-mediated non-volatile 90° and 180° magnetization rotations are realized in the Co/0.7Pb(Mg_1/3Nb_2/3)O₃-0.3PbTiO₃ multiferroic heterostructures at room temperature.[2] However, the non-volatile magnetization rotations in perovskite manganese systems, which are of significance for the design of perovskite magnetic random access memories such as perovskite magnetic tunneling junctions, are still rarely studied. Here we report an in-situ electric field manipulated nonvolatile and reversible 900-rotation of the magnetic easy-axis (MEA) in La_0.7Sr_0.3MnO₃/0.7Pb(Mg_1/3Nb_2/3)O₃-0.3PbTiO₃ (LSMO/PMN-PT) multiferroic heterostructure.

电场操纵LSMO/PMN-PT(011)多铁异质结构磁易轴90°非易失性可逆旋转

使用纯电压代替磁场或大电流来操纵多铁质异质结构中的磁性是未来低功率自旋电子学(如电写入磁读取存储器)的目标。通常，电场对磁性的操纵表现出一种挥发性效应，这种效应不能用于信息存储，[1]因为磁场的变化在电场去除后消失。近年来，在室温下实现了Co/0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3多铁异质结构中压电应变介导的90°和180°非挥发性磁化旋转[2]。然而，对于设计钙钛矿磁性隧道结等钙钛矿磁性随机存储器具有重要意义的钙钛矿-锰体系的非挥发性磁化旋转，目前还很少进行研究。本文报道了原位电场操纵La0.7Sr0.3MnO3/0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (LSMO/PMN-PT)多铁异质结构的非易失性和可逆的900转磁易轴(MEA)。
