Abstract

The transfer of spin angular momentum from a polarized current to a ferromagnet can induce reversal of magnetization and generation of spin waves. In this article, we present micromagnetic simulations of magnetization dynamics in spin valve structure under effect of spin-polarized current and external magnetic field. Unlike the previous studies, the magnetizations of pinned layer, and the free layer in this study are orthogonal. Such a configuration, which is closer to that of the spin-valve sensors, shows many interesting results such as the observation of steady and oscillatory states.
