(a) Light interaction with a spin wave in a uniform ferromagnetic thin film sitting on top of a dielectric substrate; (b) Excitation of the plasmon resonance in a ferromagnetic magnonic crystal leads to enhancement of the intensity of light scattered from the spin wave; (c–f) Some examples of plasmon resonance-supporting Permalloy magnonic crystals fabricated at the National University of Singapore (see, e.g., [86]).
