In this work, we analyse the method of forming magneto-optically active heterostructures based on magnetic layers with different magnetic properties. Layers of one type possess a high effective constant of uniaxial magnetic anisotropy for which the condition is fulfilled, where Ku is the constant of uniaxial magnetic anisotropy and is the demagnetizing energy, and layers of the second type used possess in-plane or quasi-in-plane magnetization, in which the condition holds true. The layers of the first type, which we refer to as layers of positive effective uniaxial magnetic anisotropy, may have the composition Bi2Dy1Fe4Ga1O12 and the layers of second type …
