摘　　要：This article studies the characteristics of magnetostatic surface waves (MSSW) in a ferromagnetic film attached to a semiconductor cladding with carriers and shows the existence of magnetostatic solitons in the film. The results indicate that under the influence of drifting carriers, and within some frequency ranges, MSSW can develop into magnetostatic solitons, with the group velocity and phase velocity opposite under some conditions, and the velocity magnitude is related to the carrier density.This article studies the characteristics of magnetostatic surface waves (MSSW) in a ferromagnetic film attached to a semiconductor cladding with carriers and shows the existence of magnetostatic solitons in the film.
