  The dynamics of the magnetization reversal process in permalloy films by pure spin current injection has been analyzed. We have performed micromagnetics simulations based on the Landau-Lifshitz equation taking into account both the relaxation term and spin transfer torque term caused by the pure spin current which is injected into permalloy thin films laterally. For spin injection from one side of the film sample, the magnetization reversal occurs in film samples less than 70 nm wide. This size is independent of the magnitude of the injected spin current. We also found that spin injection from two sides can reverse the magnetization in permalloy films that are several times wider.
