The dynamic modelling a crystal lattice hg2cl2 in the conditions of hydrostatic compression
The dynamic model of a crystal lattice has been applied to calculation of oscillatory spectra of crystal Hg2Cl2 in conditions of hydrostatic compression. There has been received a good conformity of calculation results to certain experimental data and phase transition theoretical principles. The dependence of soft mode fluctuations frequency on pressure was designed theoretically within the framework of valent-force approximation. It will well be coordinated to experimental data. The modelling behaviour of frequency of a soft mode is described within the framework of Landau’s phenomenological theory.
