Magnetization dynamics due to spin-transfer torque in half-metallic multilayers

Study of spin-transfer torque in half-metallic interface showed significantly different out-of-plane torque compared to traditional ferromagnetic exchange [1]. These effects lead to dramatic changes in magnetization dynamics of the system. In this work we study the behavior of magnetization of half-metallic multilayers using Landau-Lifshitz-Gilbert-Slonczewski equation. The combination of anisotropy with out-of-plane torque and Gilbert’s damping with in-plane spin transfer torque affects precession and switching of magnetization of the system.
