Low-temperature heat capacity of magnesioferrite (MgFe2O4)

The low-temperature heat capacity of magnesioferrite (MgFe2O4) was measured between 1.5 K and 300 K, and thermochemical functions were derived from the results. No heat capacity anomaly was observed. From our data, we suggest a standard entropy (298.15 K) for magnesioferrite of 120.8 +/- 0.6 J mol(-1) K-1, which is about 2.4 J mol(-1) K-1 higher than previously reported calorimetric studies; but is in rough agreement with predictions from sets of internally consistent thermodynamic data.
