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...

Critical Magnetic Field Determination of Superconducting Materials*

Abstract Using a 11.4 GHz, 50-MW, <1 μs, pulsed power source and a TE013-like mode copper cavity, we have been measuring critical magnetic fields of superconductors for accelerator cavity applications. This device can eliminate both thermal and field emission effects due to a short pulse and no electric field at the sample surface. A model of the system is presented in this paper along with a d...
