摘要

外尔半金属WTe₂有强自旋轨道耦合且能产生新奇非常规面外极化的自旋流, 是近几年的新兴热点. 同时WTe₂还具有高的电荷-自旋转换效率, 能在无外磁场辅助的情况下实现垂直磁矩确定性的翻转, 这对于高密度集成低功耗磁随机存取存储器至关重要. 本文回顾了近几年WTe₂与铁磁层组成异质结构中自旋轨道矩研究的最新进展, 包括用不同方法制备的WTe₂ (例如机械剥离和化学气相沉积)与铁磁层(例如FeNi和CoFeB等)、二维磁体(例如Fe₃GeTe₂等)组成异质结的自旋轨道矩探测和磁矩翻转的电调控研究进展. 最后, 对相关研究的发展提出展望.

Abstract

The Wely semimetal WTe₂ exhibits significant spin-orbit coupling characteristics and can generate unconventional spin current with out-of-plane polarization, which has become a hotspot in recent years. Meanwhile, WTe₂ also has high charge-spin conversion efficiency, allowing perpendicular magnetization to be switched deterministically without the assistance of an external magnetic field, which is critical for the high-density integration of low-power magnetic random-access memories. The purpose of this paper is to review the recent advances in the research on spin orbit torque in heterostructures composed of WTe₂ and ferromagnetic layers, focusing on progress of research on the detection and magnetization switching in the spin orbit torque of heterojunctions composed of WTe₂ prepared by different methods (e.g. mechanical exfoliation and chemical vapor deposition) and ferromagnetic layers such as conventional magnets (e.g, FeNi and CoFeB, etc.) and two-dimensional magnets (e.g. Fe₃GeTe₂, etc.). Finally, the prospect of related research is discussed.
