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.
