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.
