Abstract:

Based on a self-consistent thermodynamic approach previously developed for a nonmagnetic solid and applied to the paramagnetic state of nickel, we for the first time correctly separated magnetic contributions to the basic thermodynamic functions of this ferromagnet in the absence of an external magnetic field in the region of a magnetically ordered state in a vicinity of the Curie point. Self-consistent values of the thermodynamic parameters that determine the paramagnetic behavior of the basic thermodynamic functions of nickel, in particular, of molar heat capacity, thermal expansion coefficient, elastic modulus, density, and Debye temperature, have been established. Temperature dependences of the magnetic contributions to molar heat capacity C-m(T) and volume thermal expansion coefficient o(m)(T) have been found and discussed in detail. The approach developed can successfully be extended to other solids possessing magnetic long-range order.
