Heat capacity and thermodynamic functions of $\mathrm{Nd}\mathrm{Me}\mathrm{Fe}_2\mathrm{O}_5(\mathrm{Me}-\mathrm{Li},\mathrm{Na},\mathrm{K},\mathrm{Cs})$ ferrites
Annotation
The values of heat capacity of $\mathrm{Nd}\mathrm{Me}\mathrm{Fe}_2\mathrm{O}_5(\mathrm{Me}-\mathrm{Li},\mathrm{Na},\mathrm{K},\mathrm{Cs})$ ferrites in the temperature range from $298$ to $673$ K are experimentally determined. Equations of the temperature dependence of heat capacity are derived and used to calculate the thermodynamic functions $C_p^\circ(T)$, $S^\circ(T)$, $H^\circ(T)-H^\circ(298.15\mathrm{K})$, and $\Phi^{**}(T)$ of ferrites in the range identified above.
