Вертикальное Смещение Магнитооптической Петли Гистерезиса В Магнитоплазмонном Нанокомпозите

Abstract

In article the synthesis and investigation results of magneto-optical (MO) properties of thin-film nanocomposite, which is a bismuth-substituted Bi: YIG ferrite garnet layer with Au plasmon nanoparticles are representative. The effect of vertical shift of MO hysteresis loops (relative to the origin of coordinates) was detected with study of MO properties during remagnetization of the magnetoplasmon composite structure. It’s shown that the observed effect is most pronounced near the condition of localized plasmon resonance in the metal nanoparticles system which make up the magnetoplasmonic composite.
