摘要
The influence of the nonmagnetic interstitial solute (nitrogen) on the paramagnetic properties of the multicomponent iron-based alloy was studied. The spin resonance measurements have shown that the increase of the Mn content in the austenitic alloy leads to a decrease of the electron state density on the Fermi surface, D(F) up to two orders of magnitude and to the large shift of the g-factor, DELTAg > 0 The character of the temperature dependence of the g-factor gives an evidence for clusterization of the d-element atoms with ferromagnetic interaction. The increase of the state density on the Fermi surface as the interstitial solute content grows was confirmed for nitrogen concentrations 1% < C(N) < 1. 5% and it was found that D(F) decreases smoothly at the nitrogen contents C(N) > 1.5%. It was found that nitrogen content affects the process of formation of the d-clement clusters as well.
