The heat capacity of Fe 3 xCr xO 4 with the composition x = 0.6, 0.8, and 1.0 was measured from 200 to 850 K. A γ-type heat capacity anomaly due to the ferri-paramagnetic transition was observed for all compositions. The transition temperatures were 652, 563, and 451 K for the comp...
The heat capacity, Cp, of the salts FeSiF6· 6H2O and CoSiF6· 6H2O has been measured from ca. 8 to ca. 298 K. Below ca. 35 K Cp of the iron compound is anomalously high compared with Cp of the cobalt salt and of the four other fluorosilicates for which Cp has been determined...
Example:The molar heat capacity of iron is 25.10 J/(mol K), which means that it takes 25.10 Joules of heat to raise 1 mol of iron by 1 degree Kelvin. Tabulated values of molar heat capacity, Cp,of a lot of organic and inorganic substances can be found inStandard enthalpy of formation...

.Heat capacity of ferromagnetic nano-particles caused by lattice vibration will increases with the higher temperature.Heat capacity caused by surface free energy of the nano-particles will increase as the temperature gets higher and the larger the grain diameters are,the greater the thermal capacity ...
Heat capacity is one of the most characteristic and important properties when the peculiarities of magnetic nanosystems are studied. In these systems the magnetic ordering becomes obvious due to the thermal effects such as heat capacity anomalies. It was considered earlier that heat capacity change und...
