Out-of-Plane Torque Influence on Magnetization Switching and Susceptibility in Magnetic Multilayers

  • Received Date: March 07, 2010

  • Based on both the spin diffusion equation and the Landau-Lifshitz-Gilbert (LLG) equation, we demonstrate the influence of out-of-plane spin torque on magnetization switching and susceptibility in a magnetic multilayer system. The variation of spin accumulation and local magnetization with respect to time are studied in the magnetization reversal induced by spin torque. We also research the susceptibility subject to a microwave magnetic field, which is compared with the results obtained without out-of-plane torque.
