    Abstract

    The details of crystal structures in Sr1-xLaxTiO3 with the simple perovskite structure have been investigated by means of electron diffraction at room temperature. When the Sr content decreases, the crystal structure was found to change as follows; Pm3m (x=0), R3̄c (0.05≦x<0.6), and Pm3m (0.6<x≦1.0). That is, the Pbnm structure results from the condensation of both M3 and R25 modes in the Pm3m structure, which are rotation modes of the TiO6 octahedron, while only the R25 displacement is involved in the R3̄c structure.
