Metal nanostructured ferromagnetic as a possible source of optical magnetism

Abstract

It is shown analytically that plasmon-mediated magnetic response can be realized at optical frequencies in nanostructured magnetized metallic ferromagnetics under certain restrictions on their electronic subsystem. According to the results of our calculations, the occurrence of magnetic resonance in the visible spectral region is expected in the vicinity of the electron plasma frequency. The effect of a ferromagnetic film with intrinsic optical magnetism on the properties of an optical system assembled from titania nanotubes metallized with Ni is analyzed.
