摘要
The heat capacity of dimethylammoniumgallium sulfate crystals was measured using adiabatic calorimetry in the range 80–300 K before and after gamma irradiation with doses of 107 and 108 R. Heat-capacity anomalies were revealed around the ferroelastic-ferroelectric (135 K) and ferroelectric-paraelectric (119 K) phase transitions. Gamma irradiation was found to reduce the temperature stability range of the ferroelectric phase.
