Phenomenological model of surface-induced anisotropy in magnetic nanostructures
A phenomenological theory of surface-induced magnetic anisotropy has been developed to describe inhomogeneous distribution of surface interactions into the depth of nanowires with circular cross-section and spherical nanoparticles. For ellipsoidal nanoparticles and elliptical nanocylinders, by using...
