我们研究了沉积在外延压电层上的具有软垂直各向异性的 Co40Fe40B20/Co/Pd 多层中电场辅助的磁化反转。在施加电场的情况下，成核磁场和脱钉磁场均显示出高达 30% 的强烈降低。这些结果显示了辅助超低功耗自旋电子器件切换过程的良好前景。
We investigate magnetization reversal assisted by electric fields in a Co40Fe40B20/Co/Pd multilayer with soft perpendicular anisotropy deposited onto an epitaxial piezoelectric layer. Both the nucleation and depinning magnetic fields show a strong reduction of up to 30% under the application of an electric field. These results show good prospects for assisting the switching processes in ultra-low-power spintronic devices.
