Abstract
We investigated the self-induced inverse spin Hall effect in ferromagnets. Temperature (), thickness (), and angular-dependent measurements of transverse voltage in spin pumping experiments were performed with permalloy films. Results revealed nonmonotonous dependence of the self-induced transverse voltage. Qualitative agreement was found with first-principles calculations unravelling the skew scattering, side-jump, and intrinsic contributions to the -dependent spin Hall conductivity. Experimental data were similar whatever the material in contact with permalloy (oxides or metals), and revealed an increase of produced current with , demonstrating a bulk origin of the effect.
