Аннотация:We study the dependence of magnetic properties: Curie temperature, mean and local magnetic moments - on the type of crystal lattice and average number of d electrons per atom. The problem is considered in two approximations: with spin fluctuations not taken into account, in the Stoner mean field theory, and with spin fluctuations taken into account, in the dynamic spin fluctuation theory (DSFT). In the DSFT, we obtain an analogue of the Slater–Pauling curve for the mean magnetic moment at finite temperatures. Numerical results in the DSFT are in qualitative agreement with experiment: with magnetic phase diagramand dependence of magnetic moment on concentration in ferromagnetic alloys.
