Domain wall dynamics in a double-layer uniaxial magnetic film with different intensity of saturation magnetization of the layers

Motion of an isolated domain wall in a double-layered magnetic film, whose layers differ in their saturation magnetization intensity only, is investigated through solving the Slonczewski equations by a numerical method. Dependences of the threshold field and the limiting velocity of disruption of the steady state motion of the film on the saturation magnetization are obtained. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 7, pp. 37–42, July, 2007.
