The spin Hall effect of Bi-Sb alloys driven by thermally excited Dirac-like electrons

Zhendong Chi, Yong-Chang Lau, Xiandong Xu +3

We have studied the charge to spin conversion in Bi${}_{1-x}$Sb${}_x$/CoFeB heterostructures. The spin Hall conductivity (SHC) of the sputter deposited heterostructures exhibits a high…
