Abstract: We demonstrate both experimentally and numerically multifold enhancement of magneto-optical effects in subwavelength dielectric nanostructures with a magnetic surrounding exhibiting localized magnetic Mie resonances. We employ amorphous silicon nanodisks covered with a thin nickel film and achieve the 5-fold enhancement of the magneto-optical response of the hybrid magnetophotonic array of nanodisks in comparison with a thin nickel film deposited on a flat silica substrate. Our findings allow for a new basis for active and nonreciprocal photonic nanostructures and metadevices, which could be tuned by an external magnetic field.

TL;DR: In this article, the effect of magneto-optical responses up to 0.8° and 0.5% on the Faraday effect induced by magnetic dipole and Voigt effect amplification due to electric dipole Mie resonances of the magnetophotonic metasurface is demonstrated.

TL;DR: In this article, the effect of the interaction between an external magnetic field and an optically induced magnetic response of metamaterial structures was investigated and the effect was shown to be multifold enhancement of magneto-optical response of nanoantenna lattices due to the optical magnetism.

TL;DR: In this article, the Fano-type Faraday rotation spectrum in a one-dimensional magnetophotonic crystal at the Bloch surface wave (BSW) resonance was observed and the shape of the resonance was determined by the relative position and spectral splitting of the modes.

TL;DR: In this article, the enhancement mechanisms of magneto-optical effects in all-dielectric metasurfaces caused by the bound state in the continuum resonance were analyzed.
