Abstract
In this paper, we point out how the magnetization switching depends on the nanostructure geometry and on the material parameters. The micromagnetic study is carried out on multilayer nanodevices constituted by Permalloy(Py)/Cu/Py and Co/Cu/Co with different cross-sections. Results show that the switching time is strongly dependent on the magnetization of the material
