Abstract

The problem of developing a basis for dimensional (physical) statistics is posed and illustrated with statistical analysis of the thermodynamic magnetic properties of ferromagnetic nickel with allowance for magnetophonon interaction (interaction between the magnetic subsystem and the crystal lattice). By dimensional statistics is meant statistical analysis of quantities differing in nature and dimension with a unified physical model allowing a statistically optimal description of the quantities. The properties being analyzed are the temperature dependences of the (i) thermodynamic (Landau) coefficients, α(T) and β(T); (ii) reciprocal initial paramagnetic susceptibility, X −10 (T); (iii) spontaneous magnetization, M s(T); (iv) magnetization in an external field, M(T, H); and (v) magnetic part of the molar heat capacity, C m(T).
