摘要：

A simple way of analyzing the atomic displacements in perovskite alloys is used to determine the optical phonons contributing to their low-temperature ferroelectric properties. This determination (i) leads to the identification of three different kinds of solid solutions, (ii) reveals why simple theoretical models can be used in some alloys and not in others, and (iii) explains why unusual phase transitions can occur in ordered ferroelectric solid solutions.
