Abstract
The spin-charge conversion in ferromagnetic materials is a recent intriguing research topic. We report the large spin anomalous Hall effect (spin-AHE) in an L10-FePt ferromagnet. The spin anomalous Hall angle was evaluated to be ~ 0.25 for the L10-FePt from the linewidth modulation of ferromagnetic resonance spectra by dc current application. The evaluation of spin anomalous Hall angle at different configurations between applied electric current and the L10-FePt magnetization allowed us to examine the symmetry of spin-AHE. By utilizing the large spin anomalous Hall angle of L10-FePt, we also have successfully demonstrated spin-AHE-induced switching of the Permalloy magnetization.
