Domain wall dynamics in a double-layer uniaxial magnetic film with different magnetic anisotropy in the layers

摘要

Motion of an isolated domain wall in a double-layered magnetic film is investigated through solving the Slonczewski equations by a numerical method for the same gyromagnetic ratio and different anisotropy constants in the layers. Dependences of the threshold field and the limiting velocity of disruption of the steady state motion of the film on the magnetic anisotropy constant in one of the layers are obtained.
