摘要：
The thermal capacity of a sample of composition Ce2O3.02 has been determined from 5 to 350°K by adiabatic calorimetry. A cooperative anomaly with maximum at 8.5°K occurs with ΔSt = 0.83 cal/ (mol°K). The observed thermal capacity values yield for Cp, S° - S°5°K, and (G° - H°5°K)/T values of 28.05, 32.60, and - 15.74 cal/ (mol °K) for stoichiometric Ce2O3 at 298.15°K. These values are referenced to 0°K with an estimated ordering contribution.
