Current induced motion of a domain wall — •Christian Wickles and Wolfgang Belzig — Fachbereich Physik, Universität Konstanz

A quantum Boltzman approach within the framework of a mean field Stoner model is employed to study the spin-current induced motion of domain walls in ferromagnetic materials. The local magnetisation of the ferromagnet is described by an exchange field with space- and time-dependent direction. The effect of magnetic impurity and spin-orbit scattering is considered. Non-adiabaticity terms are included aswell.
