Abstract
The regularities of the magneto-optical (MO) response of the metallized surface of nanostructured lead selenide are studied. The MO hysteresis loops (MOHLs) of the equatorial Kerr effect (MOEKE) exhibit the characteristic features inherent to the presence of vortex magnetic structures in the system. The regularities of the evolution of the shape of the hysteresis loops of the MOEKE depending on the characteristic sizes of nanostructures, the thickness of the magnetic film, and the incidence angle of electromagnetic radiation are studied. It is shown that the formation of vortex magnetic structures corresponds to the minimum energy losses for remagnetization. Computer modeling of the regularities of the appearance and development of vortex magnetic structures on curved surfaces is carried out.
