Summary: In this paper, the magnetization of diluted magnetic semiconductor superlattices with a magnetic impurity of manganese is studied. It was found that the magnetization of a quasi-two-dimensional electron gas, depending on the degree of filling of the miniband superlattices, the molar concentration of the impurity, the exchange interaction constant and the spin splitting factor, changes sign and in a strictly two-dimensional case becomes positive. In a magnetic field, magnetization oscillates, and in strong magnetic fields the oscillations weaken, and their amplitude and frequency decrease. The contribution of the impurity to the magnetization is calculated. In a relatively weak magnetic field the magnetization associated with the impurity increases linearly and at a certain condition to the depending on the magnitude of the exchange constant and the impurity concentration changes its sign.
