Electrons in a ferromagnetic metal with a domain wall

Abstract

We present a theoretical description of conduction electrons interacting with a domain wall in ferromagnetic metals. The description takes into account the interaction between electrons. Within the semiclassical approximation we calculate the spin and charge distributions, particularly their modification by the domain wall. In the same approximation we calculate the local transport characteristics, including relaxation times as well as charge and spin conductivities. It is shown that these parameters are significantly modified near the wall and this modification depends on the electron-electron interaction. The spatial nonuniformity of the transport characteristics may give rise to new phenomena.
