Thermodynamic properties of CoCr2O4: specific heat and magnetic entropy
Uhlarz, M.; Pronin, A. V.; Wosnitza, J.; Prokhorov, A. S.; Bush, A. A.
We present the temperature dependence of the specific heat of CoCr2O4 between 2.08 K and 306 K in zero magnetic field. The lattice component can be described by the Komada–Westrum model with a characteristic temperature ΘKW = 541 K. The entropy of the magnetic component amounts to 33.51 J mol-1 K-1 at T = 298.15 K, in good agreement with the magnetic entropy of Co2+ and Cr3+ ions with completely quenched orbital moments. We compare our results with data available in literature.
