Abstract: In this work the results of investigations of the magneto-optical properties of Co-Ti-O nanogranular films obtained under conditions of the solid-state reaction with the oxygen exchange reaction in the CoO/Ti layered structures are presented. The formation of the granular films with composition in the area of and below a percolation threshold is shown. The magnetooptical spectra features of the obtained films with the filling factor of magnetic phase from 0.3 to 0.52 in comparison with spectra of uniform metallic films are found.

Keywords: nanogranular films, solid-state reaction, synthesis, magneto-optical properties, Kerr effect.
