Аннотация: We show that the effect of magnetic ordering in magnetic semiconductors by the mechanism of s-d(f) exchange interaction plays an important role in explaining the quantum temperature oscillations of band-electron magnetization that were discovered in the experiments of S. G. Ovchinnikov, V. K. Chernov, A. D. Balaev, N. B. Ivanova, B. P. Khrustalev, and V. A. Levshin (JETP Lett. 64, 642 (1995)). We analyze how hybridization of band and localized electrons affects the amplitude of this effect. Finally, we establish that because of strong intratomic correlations the amplitude of the oscillation effects depends to a great extent on the sign of the exchange constant J.
