Abstract
A new layered body-centered tetragonal perovskite structure was observed in polycrystalline Sr2FeMoO6 materials by transmission electron microscopy (T EM). Together with the double perovskite (DB) and the layered superstructur e with tripled c-axis (ST) reported previously, the three ordered perovskit e phases co-exists in the grain by sharing a common atomic plane of (001). The translation periodicity along the direction perpendicular to the layer plane is about 20 Angstrom. (C) 2001 Elsevier Science Ltd. All rights reser ved.
