Abstract:

Thermodynamic model calculations are performed with the aim to show that the invar behavior of a ferromagnet (when its thermal expansion coefficient is close to zero in a climatic temperature range) results from a certain optimum relation between the thermodynamic parameters characterizing the ferromagnetic state. The same is true for the covar behavior of a ferromagnet, when its thermal expansion coefficient is nonzero and almost constant in a certain temperature range. As a first approximation, calculations for simple ferromagnets are performed in terms of the thermodynamic Landau model.
