Abstract
The structural behavior of LaMnO3+delta is described. One rhombohedral and three different orthorhombic X-ray patterns have been observed. T he largest influence on the structure is the overall amount of Mn4+, b ut the La:Mn ratio and the temperature also have a significant influen ce. In the pseudobinary La2O3-Mn2O3 phase diagram, LaMnO3+delta is the only compound containing both La and Mn. This is not a line compound since a solubility range was observed on both the La-rich and the Mn-r ich sides. (C) 1995 Academic Press, Inc.
