Publikováno v: physica status solidi (b). 153:529-537

A thermodynamic theory of phase transitions in crystals with TlGaSe2 structure is developed. The nature of order parameters is discussed on the basis of spectroscopic data. A phase diagram is constructed in the plane of the model coefficients. Conclu

Publikováno v: physica status solidi (b). 153:517-527

Raman spectra of TlGaSe2 single crystals are obtained in the temperature range 85< T < 300 K, which includes the phase transition points. Fitting of the spectra, using the model of additive damped oscillators and a relaxator, yields quantitative info
