Abstract: Magnetic nanostructures make it possible to enhance magneto-optical effects by many times owing to the excitation of optical resonances. A new type of magnetic structure is proposed, which is a two-dimensional all-dielectric bismuth-substituted iron garnet grating. Enhancement of the Faraday effect in such a structure caused by the excitation of waveguide modes is described analytically, and the conditions for the resonant enhancement are revealed. The resonant enhancement of the Faraday effect in all-dielectric magnetic nanostructures has been experimentally demonstrated for the first time.
