Exact solutions of Landau–Lifshitz equation for a ferromagnet with an easy axis anisotropy, which describe the interaction of nonlinear precession wave of arbitrary amplitude with soliton-like objects such as breathers, solitary domains and domain boundaries, are obtained. Changes of internal structure and physical parameters of solitons due to the interaction with magnetization wave are analyzed. It is shown, that both solitary domains and domain boundaries move towards the wave. Conditions for the destruction of solitons by the nonlinear magnetization wave are deduced.
