Low Temperature Heat Capacity and Thermodynamic Properties of Zinc Ferrite*

The heat capacity of zinc ferrite (ZnFe,O,) has been determined over the range 5 to 350°K. Molal values of C~,S’, and HO-H,O computed from the thermal data are 32,99&t-0.03 cal/deg., 36.01 f0.03 cal/deg., and 18,00&0.02 Cal, respectively, at 298,lS”K. A co-operative thermal anomaly associated with antiferromagnetic ordering occurs at 9.5” and extends toward higher temperatures probably as a con...

Low-temperature excess heat capacity in fresnoite glass and crystal

The effect of thermal annealing on low-temperature excess heat capacity was investigated in fresnoite (Ba2TiSi2O8) glass. The amplitudes of the excess heat capacity decreased, and their positions shifted to a higher temperature by relaxation or crystallization. In particular, we revealed that the change in the excess heat capacity during transition from the glassy state to the crystalline state...

Anomalous behaviour of the low-temperature heat capacity for KCl crystals with heavy univalent impurities

The effect of low concentrations of heavy univalent Cs' and Iimpurities on the low-temperature heat capacity of KC1 gives an enhancement in the heat capacity. This anomalous behaviour has been explained on the basis of a low concentration Green's function theory. A localized perturbation model which includes mass change at the impurity site as well as changes in the nearest neighbour radial for...
