description: A technique is developed for the time efficient measurement of reflection magneto-optical effects in a wide spectral range. The spectral dependences of the rotation angle of the polarization plane and the ellipticity of the incident linearly polarized light for the region from 1 to 5 eV are obtained in films of Y3Fe5O 2 yttrium iron garnet on a substrate of GaAs arsenide in the polar Kerr effect geometry. In the region of weak absorption below 3 eV, energy-equilibrium oscillations of the measured quantities are observed associated with the interference of rays in the film. The film thickness was determined, which for the two studied samples is 2.12 and 1.32 Î¼m respectively, and the spectral dependence of the complex off-diagonal element of the permittivity tensor in the Y 3 Fe 5 O 12 film was obtained. In the region of strong absorption near 4 eV, an optical transition is determined corresponding to a high-intensity transition with charge transfer between iron ions in tetrahedral sites (Fe3+) and iron ions in octahedral sites [Fe2+]. The developed technique allows for rapid diagnostics of the magneto-optical properties of various materials in a wide spectral range.
