Abstract

The spin transport induced from an electric field in the ferromagnet with a uniform magnetization is studied microscopically. Taking into account the time dependence of the electric field and the spin relaxation due to a spin-orbit interaction at impurity, we derive the spin diffusion equation including the time evolution. We also discuss a relationship between a frequency dependence of the spin accumulation and the spin diffusion length.
