Spin Hall effect in a non-equilibrium Cu76Ir24 alloy measured at various temperatures

Research output: Contribution to journalArticlepeer-review


Non-equilibrium Cu-Ir binary alloys are interesting materials because these alloys show a large spin Hall effect (SHE) despite the non-remarkable spin Hall angles of pure Cu and pure Ir. In this study, the temperature dependence of the SHE on a non-equilibrium Cu-Ir binary alloy was investigated in order to understand the mechanism of its large SHE. We measured the spin Hall magnetoresistance for the Cu76Ir24/CoFeB bilayer at various measurement temperatures. The spin Hall conductivity remains practically constant against temperature and electrical conductivity, indicating that the side jump or the intrinsic process based on the band structure is dominant for the SHE in the present Cu76Ir24
