Abstract
Exact solutions of the Landau-Lifshitz equation are obtained for a ferromagnet with an easy-axis asymmetry which describe the interaction of a nonlinear precession wave of arbitrary amplitude with soliton-like objects such as breathers, solitary domains, and domain boundaries. Changes in the internal structure and physical parameters of solitons owing to their interaction with a magnetization wave are analyzed. Solitary domains and domain boundaries are shown to move counter to the wave. Conditions are found such that solitons are destroyed by a nonlinear magnetization wave.
