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. When a magnetic field is applied perpendicularly to the grating slits the field distribution of its optical modes and thus the mode excitation conditions are changed. Under those conditions two principal modes of the magnetic layer – TM- and TE-modes – acquire additional field components and thus turn into quasi-TM and quasi-TE-modes, respectively. In the optical far-field this modification of the modes manifests itself in the distinct alteration of the optical transmission or reflection coefficients when the structure becomes magnetized.
