Abstract

(CF4)1−x(CClF3)x shows a eutectic phase diagram with a eutectic temperature TE =69 K and a eutectic concentration xE =0.54. In the mixed crystal regime x&lt;0.015, dielectric audio frequency spectroscopy revealed the dynamics of weakly coupled CClF3 molecules performing thermally activated reorientations. An analysis of the data was performed in terms of a relaxator model including a critical comparison of different distributions of relaxation times. The static susceptibilities of the mixed crystals suggested a two-phase model of CF4, where rigid latice domains coexist with paraelastic regions. Several pure CClF3 samples were investigated using different thermal treatments. The dielectric dispersion of this compound is described by the reverse Havriliak–Negami expression and possible explanations for the origin of the relaxation spectra are discussed. The behavior of the CClF3 rich mixed crystals is considered briefly.
