Forced motion of solitary domains and domain walls in the field of a nonlinear magnetization wave

For a ferromagnet with an easy-axis anisotropy, exact solutions to the Landau-Lifshitz equations have been obtained, which describe the interaction of a nonlinear wave of the precession of arbitrary amplitude with soliton-like objects such as breathers, solitary domains, and domain walls. Changes in the internal structure and physical parameters of solitons as a result of their interaction with a magnetization wave have been analyzed. It is shown that the solitary domains and domain walls move in the direction opposite to the magnetization wave. Conditions have been found under which the nonlinear wave of magnetization destroys solitons. It has been established that the destruction of breathers can be accompanied by the generation of magnetization self-oscillations.
