Influence of the ionic radii on the transition temperature of tilted perovskites

Journal Article:

Abstract

It is shown that the temperature of the transition to the cubic phase in the perovskites with tilted octahedra, considering compounds with the same central ion, is a decreasing function of the tolerance factor. An explanation is given in terms of empty spaces of the crystal structure and the rms thermal necessary to fill them.
