"The heat capacity was measured using a standard dc pulse-relaxation technique on samples of typically 200 mg. The data in magnetic field were taken between 0 T and 7.7 T where the magnetoresistance of the Cermac thermometer and the sample heater were both less than 0.5%. A carbon-chip resistor monitored the sample temperature and was calibrated against the Cermac thermometer during every run. Errors in the absolute values of the heat capcacity are less than 1% at zero field and 2% in a magnetic field, and the typical scatter of the data is less than a few tenths of a percent."
