摘要：

Hall coefficient RH and resistivity ρ{variant} for Pb0.56Sn0.44Te crystal were measured as a function of temperature and pressure in the region of the ferroelectric phase transition. It enabled to obtain the pressure dependence of the phase transition temperature. Analysis of the experimental data showed that the lattice anharmonicity gives the dominant contribution to the phase transition mechanism. © 1979.
