Abstract:
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 MoS〈sub〉2〈/sub〉, WSe〈sub〉2〈/sub〉, WS〈sub〉2〈/sub〉, WTe〈sub〉2〈/sub〉, TaTe〈sub〉2〈/sub〉, MoTe〈sub〉2〈/sub〉, NbSe〈sub〉2〈/sub〉, PtTe〈sub〉2〈/sub〉, TaS〈sub〉2〈/sub〉, etc.) and magnetic two-dimensional materials (such as Fe〈sub〉3〈/sub〉GeTe〈sub〉2〈/sub〉, Cr〈sub〉2〈/sub〉Ge〈sub〉2〈/sub〉Te〈sub〉6〈/sub〉, 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.
