抄録

The spin-Hall effect (SHE) and the inverse spin-Hall effect (ISHE) coupled with magnetization dynamics were investigated using a simple Nisi Fe 19/Pt film. A spin current generated by magnetization dynamics was detected electrically using ISHE. The observed magnetic field angle dependence of the ISHE signal is well reproduced by a model calculation based on the dc spin pumping and ISHE. In the same system, we found that spin relaxation in the Nisi Fe19 layer is manipulated electrically using SHE. An electric current applied to the Pt layer exerts the spin torque on the entire magnetization of the Ni81 Fe19 layer via the macroscopic spin transfer induced by SHE, which modulates spin relaxation in the Nisi Fe19 layer. This spin-relaxation modulation enables quantitative measurements of spin currents without assuming any microscopic parameters.
