We present our study on a novel magneto-optical phenomenon observed in a hybrid metal-dielectric structure consisting of a one-dimensional gold grating on top of a magnetic waveguide layer. A magnetic field applied perpendicularly to the grating slits modifies the field distribution of the optical modes and thus changes the mode excitation conditions. In the optical far-field, this manifests in the alteration of the optical transmittance or reflectance.
