| Research Abstract |
We theoretically clarified novel phenomena due to the interaction between magnetization and current in a ferromagnetic metal. Concretely, we worked out the detailed calculation of current-induced spin torques and spin-depended motive force accompanied by a magnetization dynamics. Both cases, we studied the spin and charge transports in a ferromagnetic metal, which is included in the effect of spin-flip scattering due to magnetic impurities.
