Abstract
The temperature behavior of magnetic, thermal and transport properties of ferromagnetic transition metals is shown to be mainly determined by the electron spin density fluctuations. The effect of the fluctuation dynamics on magnetism and heat capacity of iron is considered. The fluctuation theory of resistivity and ferromagnetic Hall effect is developed. The influence of thermal lattice vibrations on magnetism is evaluated. A description of the low-energy electron excitations with the help of a thermodynamic ensemble of the spin spiral configurations is proposed. In such approach the magnetic characteristics, the form of the photoemission spectra and the short range magnetic order above the Curie temperature TC are found simultaneously.
