A comparison of spin-polarized current driven magnetization reversal in Co/Cu/Co magnetic multilayers

Co/Cu/Co multilayers have been used in order to build magnetic devices for spintronic applications. The anisotropy of thin Co nanostructures is not well known, so it is difficult to take it into account in a precise way for micromagnetic simulations. Starting from experimental data in order to determine the anisotropy constant of thin Co, we study and compare the fast switching magnetization processes of three different structures.
