Provides insight into magnetic-lattice coupling mechanisms
Abstract
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.
