Nonlinear Spin Dynamics in Magnetic Mesostructures Induced by Spin Polarized Autoemission

Abstract:

The work is devoted to the discussion of magnetic dynamics features in mesoscopic magnetic structures under the action of spin transport and spin-torque transfer in the nanopillar structures. Tunneling magnetic structure consisting of autoemission cathode and patterned magnetic anode is considered. Main bifurcation changes in the states of a dynamical system, that models mesoscopic structure, are discussed for varied spin polarized current and an external magnetic field.
