Abstract
The effective spin pressure induced by an electric current on a domain wall in a ferromagnet is determined using a simple classical model, which allows us to extend previous theories to arbitrary domain wall widths. In particular, the role of spatially non-uniform components of the torques are analyzed in detail. We find that the effect of the current is mainly to distort the domain wall which should enhance de-pinning. We also find that in the limit of thin domain walls the current-induced pressure changes sign.
