在具有自旋-轨道耦合效应的材料中, 电荷流能够诱导产生垂直于电流方向的纯自旋流, 当其注入近邻的磁性层时, 会对其磁矩产生自旋-轨道矩. 自旋-轨道矩能够快速、高效地翻转磁矩, 为开发高性能的自旋电子器件提供了一种极佳的磁矩操控方式. 二维材料由于具有很多的优点, 如种类丰富、具有多样化的晶体结构和对称性、能够克服晶格失配形成高质量的异质结、具有强自旋-轨道耦合、电导率可调等, 为研究自旋-轨道矩提供了独特的平台, 因此引起了人们的广泛关注. 本文涵盖了近年来与二维材料及其异质结构中自旋-轨道矩研究相关的最新进展, 主要包括了基于非磁性二维材料(如MoS2, WSe2, WS2, WTe2, TaTe2, MoTe2, NbSe2, PtTe2, TaS2等)和磁性二维材料(如Fe3GeTe2, Cr2Ge2Te6等)的异质结中自旋-轨道矩的产生、表征和对磁矩的操控等. 最后指出了目前研究中尚未解决的问题与挑战.The spin-orbit torque generated by charge current in a strong spin-orbit coupling material provides a fast and efficient way to manipulate the magnetic moment in adjacent magnetic layers, which is expected to be used for developing low-power, high-performance spintronic devices. Two-dimensional materials have attracted great attention, for example, they have abundant species, a variety of crystal structures and symmetries, good adjustability of spin-orbit coupling strength and conductivity, and good ability to overcome the lattice mismatch to form high-quality heterojunctions, thereby providing a unique platform for studying the spin-orbit torques. This paper covers the latest research progress of spin-orbital torques in two-dimensional materials and their heterostructures, including their generations, characteristics, and magnetization manipulations in the heterostructures based on non-magnetic two-dimensional materials (such as MoS2, WSe2, WS2, WTe2, TaTe2, MoTe2, NbSe2, PtTe2, TaS2, etc.) and magnetic two-dimensional materials (such as Fe3GeTe2, Cr2Ge2Te6, etc.). Finally, some problems remaining to be solved and challenges are pointed out, and the possible research directions and potential applications of two-dimensional material spin-orbit torque are also proposed.
