Enhanced magneto-optical effects in hybrid Ni-Si metasurfaces

Abstract

The multifold enhancement of the Faraday effect induced by magnetic dipole and Voigt effect amplification due to electric dipole Mie resonances of the magnetophotonic metasurface is demonstrated. The values of the magneto-optical responses up to 0.8° and 0.5% are experimentally observed for the metasurface with an ultrathin ferromagnetic layer. The results can be used for the development of novel active magnetophotonic metadevices.
