Abstract

Electron diffraction and high resolution electron microscope observation for CaMnO3−x (x=0. 02 and 0. 05) showed unique features of the ordered structure. A coherent intergrowth of several phases with a long period in CaMnO3−x composed of extended perovekite units was observed. The relation in crystallography in the family of ordered perovskite related oxides in CaMnO3−x, which could help towards an understanding of magnetic properties and catalytic action of CaMnO3−x, is discussed.
