摘要：

Successive structural transitions of KCdF3 and K0.5Rb0.5CdF3 have been studied by means of thermal diffusivity, polarized light scattering and X-ray diffraction. It is found that transitions occur at about 460 K and 475 K in KCdF3, and at 222 K, 232 K, 250 K, 258 K and 268 K in K0.5Rb0.5CdF3. The partial exchange between K+ and Rb+ ions gives rise to simultaneous condensation of the M3 and RJ5 soft phonons. © 1990, Taylor & Francis Group, LLC. All rights reserved.
