Recent Developments in Co-Based Heusler Alloys Research
Co-based Heusler alloy is a kind of intermetallic compound with highly ordered crystal structure.Its chemical composition is usually expressed by Co2XY,where X is a transition metal element and Y is a main group element.Compared with other materials,it has higher spin polarizability,higher Curie temperature and lower damping factor.Based on these excellent characteristics,Co-based Heusler alloy has great application prospects in spin valves,tunnel junctions and semiconductor spin field effect transistors.In this paper we reviewed recent international studies on Co-based Heusler alloys on perpendicular magnetic anisotropy and spin-orbit torque.We also summarized the influencing factors of perpendicular magnetic anisotropy and spin-orbit torque from the aspects of alloy composition,microstructure,magnetic layer thickness,buffer layer material,oxide layer material,element diffusion,etc.,which will help us better understand its deep-seated physical mechanism,as well as the challenges and prospects in future research.
