Currently, expanding the elemental memory of computers and creating new generations of elemental bases for telecommunication systems are among the most important tasks for the national economy. However, further development of all these directions requires solving problems of a fundamental nature, such as achieving the superparamagnetic limit (which limits recording density), a relatively slow change in the magnetic state under the influence of magnetic field pulses (limiting recording speed), and a small magnitude of magneto-optical effects (limiting their use in integrated photonics). To solve these problems, the development and creation of new hybrid magnetic nanostructures that combine magnetic and non-magnetic materials - dielectrics, semiconductors, and metals - in various combinations is of particular relevance. In such structures, a significant enhancement of non-reciprocal linear and nonlinear optical and magneto-optical phenomena is possible, as well as the manifestation of new effects (for example, the effects of magneto-optical spatial dispersion). This article explores the reflection and transmission of light from a magnetic layer on a transparent (glass) substrate. As a result, formulas were obtained for the equatorial Kerr effect in reflected and transmitted light. These results are necessary for interpreting experimental data on the equatorial Kerr effect.
