Аннотация: The Raman spectra of Rb2KInF6 elpasolite crystal have been studied in a wide temperature range, including two phase transitions: from the cubic phase to the tetragonal phase and then to the monoclinic phase. Several anomalies of internal modes of InF6 octahedra and low-frequency lattice vibrations, which are related to the structurПоказать полностьюal changes at the transition points, have been found and quantitatively analyzed. The results of a quantitative analysis of the temperature dependences of the parameters of spectral lines are in good agreement with the thermodynamic data on the phase transitions. © Pleiades Publishing, Inc., 2011.
