Abstarct. The dependences of the Faraday rotation angle and the dispersion properties of magnetic circular dichroism in magnetic dielectric nanostructures are theoretically investigated. The spectral properties are analyzed, i.e. frequency dependences of the differences in refractive indices and absorption coefficients of dielectric crystals, which determine the characteristics of magneto-optical phenomena. The conditions in which the values ​​of the above values ​​can have extreme values ​​are determined. It is shown that their maximum values ​​are inversely proportional to the attenuation frequency of the electron wave. Therefore, at low absorption, it is possible to significantly increase the magnitude of the studied magneto-optical phenomena. It is noted that the studied anomalies can find applications in devices based on magnetooptics for telecommunications and photonics.

Key words: magneto-optical phenomena, Faraday rotation angle, ellipticity angle.
