Abstract:

In this work we calculate the effect of spin fluctuations on a weak itinerant antiferromagnetism of transition metals alloys described by a nesting model with the presence of both the nesting parts at the Fermi surface and the so-called `'electron reservoir''. It is shown that the presence of `'electron reservoir'' with the large exchange enhancement factor of spin fluctuations leads to a decrease of the Neel temperature as compared to its value estimated in the mean-field approximation. A mechanism of magnetic order destruction, which is not associated with the scattering of the nesting parts electronic states on the `'electron reservoir'' spin fluctuations, is discussed. An extensive discussion of the thermophysical properties for this model, and of the physical and experimental implications of the results are presented.
