The heat capacity of synthetic Cu3AsS4 (enargite) was measured by quasi-adiabatic calorimetry from the temperatures 5 K to 355 K and by differential scanning calorimetry from T=339 K to T=720 K. Heat-capacity anomalies were observed at T=(58.520.5) The causes of the anomalies are unknown. At T=298.
A description of a calorimeter which determines the heat capacity of samples of different shape, in the temperature range 2.3 to 25 K and in magnetic fields up to 4.5 7", is presented in this paper. Allen-Bradley~carbon resistors were used as thermometers and calibration was done against a Ge-thermo
