摘要：
The motion of an isolated domain wall in a two-layered uniaxial magnetic film has been investigated by solving Slonczewski equations by the progonka method with allowance for the demagnetizing fields of the layers. Perpendicular to the plane of the domain wall, there was applied an in-plane external magnetic field, whose intensity was varied. Static configurations of a twisted domain wall have been calculated. In the dependence of the domain-wall velocity on the magnetic field applied along the normal to the film plane, additional maxima have been revealed in the range of middle fields. The dependences of the position of the domain wall and of the phase angle on the time and the coordinate along the normal to the film plane have been calculated.
