  Abstract:  The interaction between spin polarized current and magnetization is extensively studied by means of experimental and theoretical approaches. Up today the models used to describe the magnetization dynamic are based on the Landau-Lifshitz-Gilbert equation with an additional spin torque term proposed by Slonczewski [1]. Recently a macrospin approach was suggested [2] in which the spin-torque term is extract from transport diffusion equation. By this way structures with two or more magnetic coupled layers may be studied. Here we propose to generalize this approach by coupling full 3D micromagnetic computation and spin diffusion equation.
