【 摘 要 】

We consider a model of current-induced magnetization dynamics described by the Landau-Lifshitz-Gilbert (LLG) equations of the magnetization, in which an additional current dependent term is added. Two methods, namely Faedo-Galerkin/Penalty (FGP) method and hyperbolic regularization method are used to show the existence of finite energy global weak solutions. (c) 2010 Elsevier Inc.
