In the integral magneto-optical response of the three-layer structure Co(6 nm)/Ru(10 nm)/Co(10 nm)/Si (100) the contributions of various individual cobalt layers have been identified. A method has been developed and described that allows the magnetic properties of individual magnetic layers in three-layer systems to be analyzed based on the analysis of magneto-optical dependencies, identifying the directions of magnetic anisotropy. The developed method allowed us to establish that the properties of the magnetic anisotropy of cobalt films in a multilayer structure depend on the properties of the buffer layer and the substrate, the interactions at the interfaces, and the mechanical stresses as well as to determine the directions of the magnetic anisotropy axes in each layer.
