The optical and magneto-optical properties of the DyxCo1-x/Bi/NiFe three-layer systems are presented. The magneto-optical Kerr effect to study the temperature dependence of the magnetization and spectroscopic ellipsometry to obtain optical constants were used. It is shown that the thickness of the bismuth interlayer affects the exchange interaction between the NiFe and DyCo layers, which is manifested in a change of the magnetisation compensation temperature.
