We propose an explanation for the experimentally observed temperature hysteresis of magnetization in single crystals of lanthanum manganite (La0.8Sr0.2MnO3). The phenomenon is interpreted within the framework of a double-exchange model with allowance for the interaction of the magnetic subsystem with a bistable mode of the tilting-rotational oscillations in the correlated sublattice of MnO6 octahedra.
