Abstract

Exploring new strategies to manipulate the order parameter of magnetic materials by electrical means is of great importance not only for advancing our understanding of fundamental magnetism but also for unlocking potential applications. A well-established concept uses gate voltages to control magnetic properties by modulating the carrier population in a capacitor structure. Here we show that, in Pt/Al/Fe/GaAs(001) multilayers, the application of an in-plane charge current in Pt leads to a shift in the ferromagnetic resonance field depending on the microwave frequency when the Fe film is sufficiently thin. The experimental observation is interpreted as a current-induced modification of the magnetocrystalline anisotropy ΔH of Fe. We show that (1) ΔH decreases with increasing Fe film thickness and is connected to the damping-like torque; and (2) ΔH depends not only on the polarity of charge current but also on the magnetization direction, that is, ΔH has an opposite sign when the magnetization direction is reversed. The symmetry of the modification is consistent with a current-induced spin and/or orbit accumulation, which, respectively, act on the spin and/or orbit component of the magnetization. In this study, as Pt is regarded as a typical spin current source, the spin current can play a dominant part. The control of magnetism by a spin current results from the modified exchange splitting of the majority and minority spin bands, providing functionality that was previously unknown and could be useful in advanced spintronic devices.

摘要

探索通过电学手段操纵磁性材料的序参量的新策略，不仅对于推进我们对基础磁学的理解具有重要意义，而且对于发掘潜在应用也具有重要意义。一个成熟的概念是利用栅极电压通过调节电容器结构中的载流子数量来控制磁性。在这里，我们展示了在 Pt/Al/Fe/GaAs(001)多层膜中，当 Fe 膜足够薄时，在 Pt 中施加平面内电流会导致铁磁共振场随微波频率的变化。实验观察被解释为电流诱导的 Fe 磁晶各向异性 ΔH 的变化。我们表明：（1）ΔH 随 Fe 膜厚度的增加而减小，并与阻尼扭矩有关；（2）ΔH 不仅取决于电荷电流的极性，还取决于磁化方向，即当磁化方向反转时，ΔH 具有相反的符号。这种修饰的对称性与电流诱导的自旋和/或轨道积累一致，它们分别作用于磁化的自旋和/或轨道分量。在这项研究中，由于 Pt 被视为典型的自旋电流源，因此自旋电流可以发挥主导作用。自旋电流对磁性的控制源于多数和少数自旋能带的交换劈裂的修正，这提供了以前未知的功能，可能对先进的自旋电子器件有用。
