Abstracts

EN

Current-induced spin accumulation in a domain wall and the associated spin torque exerted on the wall are analyzed theoretically. The considerations are limited to a relatively thick Néel domain wall in a bulk ferromagnetic metal. The current-induced spin density is calculated using the linear response theory and the Green function formalism.
