Аннотация: Using the adiabatic calorimeter the heat capacity of K2ZnCl 4 and K2CoCl4 crystals was measured in temperature range 100?300 K. The entropy change for ferroelastic phase transition was estimated to be ? S=0.34 (Zn) and 0.33 (Co) JВ·mol-1K-1. The effect of hydrostatic pressure on the phase transition was investigated for both crystals.
