Strengthen of magnetic anisotropy of Au/Co/Au nanostructure by surface plasmon resonance

Abstract We experimentally demonstrated the increase of in-plane magnetic anisotropy in Au/Co/Au nanostructures by localized surface plasmon resonance (LSPR). When an array of Au/Co/Au square patch nanostructures was illuminated with linearly polarized light whose wavelength was 750 nm, the localize...
