Low Temperature Heat Capacity and Thermodynamic Properties of Zinc Ferrite*

نویسنده

  • EDGAR F. WESTRUM
چکیده

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 consequence of persisting short range order.

Chemical Synthesis of Nano-Crystalline Nickel-Zinc Ferrite as a Magnetic Pigment

The nano-crystalline nickel-zinc ferrite was prepared via chemical synthesis. Zinc nitrate, nickel nitrate, iron nitrate hydrate, citric acid and ethylene glycol were used as precursor materials. Crystallization behavior of the precursor was studied by X-ray diffraction (XRD). Nanoparticle phases can change amorphous to spinel ferrite depending on the calcination temperature and crystallite siz...

Calculation of Thermodynamic Properties of the Quasi-one Dimensional Liquid 3He at Finite Temperature

We have used a variational approach to calculate some thermodynamic properties of the quasi-one dimensional liquid 3He such as the energy, entropy, free energy, equation of state and heat capacity at finite temperature. We have employed the Lennard-Jones potential as the inter-atomic interaction. We have seen that the total energy increases by increasing both temperature and density....

Low-temperature Heat Capacities and Thermo- Dynamic Properties of Zinc Ferrites-ii Effect of Thermal History and Metallic Additives*

The heat capacities of annealed and quenched samples of Lio.osZno.poFea.as04 and of quenched ZnFqO, have been determined over the range .5-350°K. Addition of lithium to zinc ferrite lowers the temperature of the co-operative thermal anomaly associated with antiferromagnetic ordering transition in accord with theory, and quenching of either material results in nearly complete disappearance of th...

Temperature dependence of magnetic properties of heat treated cobalt ferrite

This study demonstrates the effectiveness of heat treatment in optimizing the magneticproperties of cobalt ferrite, compared to other methods such as cation substitution. It also shows how the magnetic properties of the heat treated cobalt ferrite vary under differenttemperature conditions. Saturation magnetization increased more due to heat treatment than due to Zn-substitution; a cation subst...
