Abstract

LaMnO3 compositions possessing orthorhombic, rhombohedral and cubic structures and containing 12, 24 and 33% Mn4+ respectively have been investigated by X-ray diffraction, electron diffraction and high resolution electron microscopy. The study shows that the defect structure of LaMnO3 is best described in terms of the random distribution of La and Mn vacancies, rather than by anion excess. Density measurements confirm the cation vacancy model involving an equal number of La and Mn vacancies.
