A Raman-scattering study of disorder in PbF2 at high temperatures
Journal of Physics C: Solid State Physics 10:5 (1977)
Abstract:
Extensive disorder occurs in the anion sublattice of PbF2 above a temperature TC approximately=705K. The nature of this disorder has been studied using Raman scattering at high temperatures and also a simple theoretical model which takes account of the effects of anharmonicity and defect-induced scattering on the Raman spectrum. Quite good agreement is obtained between theory and experiment.PIEZO-RAMAN AND MAGNETO-RAMAN STUDIES OF ZN ACCEPTOR IN GAP

Raman scattering study of phase transitions in RbCaF3
Solid State Communications 18:9-10 (1976) 1239-1241
Abstract:
Recent experiments on RbCaF3 have indicated the occurence of structural phase transitions at low temperature. The Raman data presented here confirm the transition at 200 K to be similar to the cubic-tetragonal transition occuring in SrTiO3 and KMnF3: soft modes of A1g and Eg symmetry are observed and the spectrum is consistent with D4h crystal symmetry. At 45 K the frequency and damping of the A1g mode begin to increase with further decrease in temperature, both of which suggest the the emergence of a new low-frequency mode of A1 symmetry at this temperature. © 1976.Light scattering study of the onset of disorder in solid electrolytes at high temperatures
