AbstractThe Raman spectra of an Rb_2KLuF_6 crystal are studied in the temperature range from 8 to 375 K, which includes two phase transitions: one of which proceeds from a cubic to a tetragonal phase, while the other transition takes place from a tetragonal to a monoclinic phase. An analysis of the temperature dependences of parameters of spectral lines shows that the former transition is of the second kind, while the latter transition is of the first kind, close to the tricritical point. It is shown that the structural phase transitions in the Rb_2KLuF_6 double perovskite are not associated with disordering. The former transition is associated with rotations of LuF_6 octahedra around the fourth-order axis, while the latter transition is related with rotations of octahedra and displacements of rubidium ions.

Exchange Of Stability

We present a lattice dynamics model for describing structural phase transitions in a one-dimensional setting. The model comprises of a chain of discrete masses interacting with nearest neighbours. In order to drive a temperature dependent exchange of stability between two phases, we allow the interatomic potential to be dependent on the temperature. The system exhibits thermal phase transitions accompanied by latent heat.
