RAMAN-SCATTERING STUDY OF PHASE-TRANSITIONS IN RBCAF-3
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 an...
