Quasi-one-dimensional magnetic solitons

The monograph contains a complete and closed presentation of the current state of the theory of quasi-one-dimensional magnetic solitons. In addition to the traditional description of the nonlinear dynamics of magnetics using the Landau - Lifshitz equations, the method of phenomenological Lagrangians of spin waves is set. The most effective methods for integrating nonlinear equations - the method of the inverse problem of scattering and the procedure of dressing - are used to build and analyze soliton solutions of basic models of magnetism theory: Landau equations - Lifshitsa for an isotropic ferromagnet, ferromagnets with quadratic anisotropy magnetization, two-stage ferrimagnets, and chiral Models for multi-performing magnets. Special options for the reductive perturbation theory are developed to study the weakly monitoring dynamics of exchange-magnetostatic waves in the plates of the final thickness, as well as magnetoelastic solitons. In the framework of the Sinus-Gordon model, the stronglyline dynamics in the spiral structures of the magnets without the center of inversion is analyzically described. The book is addressed to researchers, graduate students and students of universities of relevant specialties
