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. 相似文献

Out-of-plane angular dependence of ferromagnetic resonance spectra was measured in sputtered Co/Pt multilayers and analyzed with the Landau-Lifshitz-Gilbert equation. The effective demagnetizing field 4πMeff is found to increase with decreasing tPt and decreasing 1/tco, which can be considered as a result of interplay between the interlayer coupling and a lowdimensional effect. The g factor increases with increasing tpt and decreasing tCo, indicating contribution of spin-polarization of Pt atoms and additional contribution of orbital moment of Co atoms. The in-plane resonance line-width increases with decreasing too and increases with increasing tPt. 相似文献
