Abstract: We use the dressing method to find exact solutions of the Landau–Lifshitz equation for a ferromagnet with light-axis anisotropy. These solutions describe the interaction of a nonlinear precession wave of arbitrary amplitude with solitons. We analyze the change of the internal structure and the physical parameters of the solitons as a result of their interaction with the magnetization wave. We find an infinite series of integrals of motion that stabilize the soliton on the background of the pumping wave.

Keywords: breather, domain boundary, nonlinear magnetization wave, Landau–Lifshitz equation, Riemann problem, dressing method.
