Fluctuations of structural transformations in La0.95Ba0.05Mn0.9857Fe0.02O3+δ under heat treatment

Abstract The structural transformations in polycrystalline Ba-doped lanthanum manganite La 0.95 Ba 0.05 Mn 0.98 Fe 0.02 O 3+ δ under heat treatment in a vacuum have been studied by Mossbauer spectroscopy and X-ray diffraction analysis. It has been experimentally shown that the unusual fluctuation behavior of structural transformations in the compound annealed in a vacuum versus annealing time and/or temperature. We suppose that this behavior is related to stochastic processes.
