Abstract

A magneto-plasmonic nanostructure is disclosed. The structure includes a substrate, and a magneto-plasmonic stack, comprising a nano-sized plasmonic resonator, a nanomagnet, and a capping layer, wherein the nano-sized plasmonic resonator is configured to receive circularly polarized light at an intensity to thereby increase normal component of plasmon-generated opto-magnetic field, H, at least at the interface of one of i) the nano-sized plasmonic resonator and the nanomagnet, or ii) the nanomagnet and the capping layer, whereby the Hdirection is perpendicular to the rotational direction of the circularly polarized light and the nanomagnets in the magneto-plasmonic stack switches its magnetic moment in response to a change of the Hdirection in response to a change of the rotational direction of the circularly polarized light.
