Alternating current calorimetry at very high pressure and low temperature

Description

The specific heat of CePd2.02Ge1.98 has been measured with an ac calorimetric technique up to 22 GPa for temperatures in the range 0.3 K ≤T ≤10 K. A thermocouple allowed the temperature oscillations to be read when an ac heating current was sent through the sample. The inverse of the thermovoltage Vac recorded at low temperature exhibits a pronounced anomaly as a function of pressure. It is shown that 1/Vac extrapolated to zero temperature is a measure of the Sommerfeld coefficient γ
