Abstract: | 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.
