Abstract
This review presents the results of investigations into the conditions of the emergence, characteristic features of the internal structure, and propagation of soliton states of magnetization in a composite ferromagnet-insulator-metal structure in the magnetostatic approximation. Structure of nonlinear states with a fine internal structure (two-parameter breathers and their periodic generalizations) are analyzed. The possibility of the formation of coupled states—“compound solitons” consisting of a kink-antikink pairs—is shown. The problems of the interaction of two magnetostatic waves simultaneously propagating in a film in a nonlinear regime, as well as of the interaction of “bright” and “dark” solitons with an external monochromatic radiation, are discussed. Results of a numerical simulation and some experimental investigations are given.
