Abstract

A cerium-doped Sr TiO3 compound with the composition Sr0.4Ce0.4TiO3 has been produced by conventional solid-state processing. The structure of this compound was analyzed by X-ray, electron, and neutron diffraction. While no superlattice can be observed via X-ray diffraction, both electron and neutron diffraction show evidence of a noncubic supercell caused by antiphase tilting of oxygen octahedra. The most likely space group is C2/c, corresponding to an a-b-b-tilt system. Octahedra are tilted by ̃5̊ about the pseudo-cubic a-axis and ̃1.5̊ about the pseudo-cubic b-and c-axes.
