Magneto-optical interactions in magnetically ordered materials allow photons to be manipulated by a magnetic field and to excite magnon oscillations with light. The surface of the magnetic material plays a crucial role in these processes: the magnitude and nature of the magneto-optical effects can be significantly altered due to boundary conditions and the excitation of surface modes.

Nanostructuring the surface of a material opens up new opportunities, allowing not only to enhance optomagnetic interactions, but also to achieve new effects. Symmetry of the structure plays a crucial role. This report will discuss our recent findings in this field. This work was supported by Russian Science Foundation project (№ 24-42-02008).
