The concept of the rapidly developing area of high-index resonant meta-optics is extended to the field of mag- netically active materials. We numerically analyze magneto-optical response of hybrid nickel-silicon (Ni/Si) nanoantennas in comparison with an all-dielectric analog based on the bismuth substituted iron yttrium garnet- silicon (Bi:YIG/Si) nanoantennas. The results demonstrate the multifold enhancement of the magneto-optical effects due to the Mie-type resonances excitation in the structure. To further optimize the magneto-optical re- sponse and achieve a significant enhancement of the effect, the metasurfaces composed of Ni/Si nanoantennas of the different shape and configuration are numerically simulated. The magneto-optical effects can be significantly enhanced by means of the specific design of these hybrid metasurfaces.
