Isolation of the magnetic contribution to the thermal expansion of nickel at ferromagnetic transformation on the base of analysis of $\beta(C_p)$ correlation dependence
Annotation
A significant result of the analysis of the correlation dependence of the coefficient of volumetric thermal expansion $\beta$ on the isobaric heat capacity $C_p$ of a substance undergoing a phase transformation can be the thermodynamically correct isolation of an additional contribution to one of these two quantities if the other has been studied sufficiently fully. The magnetic contribution to the expansion coefficient of nickel undergoing ferromagnetic ordering at the Curie point $T_{\mathrm{C}} = 631$ K serves as an illustration of the model approach.
