Abstract:The stability of quasi-soliton excitations localized in a magnet near the region of excitation by a high-frequency external field has been studied within the framework of two models. They include nonlinear regions strongly excited by external pumping and regions of subsystems interacting with them, considered in the linear approximation. In the first model, the linear region is considered in the long-wavelength approximation for a system of finite length with distributed parameters. The second model considers … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
