Enhanced Magneto-Optics and Size Effects in Ferromagnetic Nanowire Arrays

A nanostructured material, composed of hexagonally arranged ferromagnetic nanowires, is fabricated. This material is found to exhibit an enhancement of the Kerr rotation, as well as a strong dependence on the nanowire diameter. Its origin is found to be a plasmon‐like structure that propagates along...

Description
Summary:A nanostructured material, composed of hexagonally arranged ferromagnetic nanowires, is fabricated. This material is found to exhibit an enhancement of the Kerr rotation, as well as a strong dependence on the nanowire diameter. Its origin is found to be a plasmon‐like structure that propagates along the ferromagnetic wires.
