Dynamics of domain walls in the field of an acoustic wave propagate in a plane of domain wall
We study the drift of a 180-degree domain wall in a ferrimagnet with two non-equivalent sublattices in the elastic-stress field generated by an acoustic wave. Sound wave propagation in plane of domain wall. The dependence of the drift velocity on the amplitude and polarization of the acoustic wave have been obtained. The analysis of long-wave and short-wave limits is carried out. The antiferromagnetic and ferromagnetic limits are explored too. The conditions of the drift of a stripe domain structure in ferrimagnets are obtained.
