Abstract It is shown that in a layered medium consisting of a magnetic metal (Co) and a nonmagnetic insulator (TiO2), the layer thickness being less than the wavelength of the light, a fundamental change occurs in the character of the Faraday-effect spectra if the number of layers is sufficiently large. When the number of pairs of layers changes from 5 to 10, a maximum appears near ~ 1.7 eV in the Faraday rotation spectrum and the ellipticity passes through zero. The results obtained are compared with the existing theory of the Faraday effect in granular structures consisting of a magnetic metal and nonmagnetic insulator. The surface plasmon energy in thin Co layers is estimated.
