Abstract: Co-Ti-O nanogranular films with different volume concentrations of a magnetic phase and Co/Ti-O layered structures with different numbers of layer pairs are studied by the magneto-optical Kerr effect. It is shown that, unlike the case of homogeneous metal films, the magneto-optical spectra of the nanogranular films exhibit resonance with a significant increase in the Kerr rotation angle in the wavelength range 500-700 nm. It is found that the Kerr rotation angle of the Co/Ti-O layer structures in the wavelength range 500-600 nm grows by an order of magnitude as compared to its value for ordinary Co films.

Abstract: Data on the magnetic properties of polycrystalline Pr0.7Ca0.3MnO3 manganite films obtained for the first time by extraction pyrolysis are presented. The effect of synthesis temperature on the magnetic properties of the manganite films is shown.
