摘要：

A microstructural study of the perovskite La0.5Li0.5TiO3 is presented. A new, tetragonal cell, a = 2(1/2)a(p) and c = 2a(p), is proposed on the basis of the cubic perovskite subcell (a(p) similar to 3.8 Angstrom). By transmission electron microscopy a microdomain twinned structure has been observed. The twinning corresponds to the three possible orientations of the doubled c-axis. Besides these twinned domains, other domains have also been detected where fringe spacings corresponding to 2a(p) x 2a(p) are present. This seems to indicate the alternation of lanthanum and lithium along the [001] direction. (C) 1995 Academic Press, Inc.
