Enhanced magneto-optical effects in dielectric Mie-resonant metasurfaces

The multifold enhancement of the Faraday effect induced by magnetic dipole and Voigt effect amplification due to electric dipoleMie 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 thedevelopment of novel active magnetophotonic metadevices.
