It is shown that the variations of susceptibility resulting from deviations from stoichiometry are associated with the electronic spectrum features of these compounds. Using magnetic susceptibility as a tool for structural order–disorder transition analysis is discussed. The lower susceptibility of the nonstoichiometric carbides is due to short-range ordering, changing the contribution of orbital paramagnetism. The long- and short-range order parameters have been estimated for NbCy, TaCy, TiCy, and HfCy based on the experimental susceptibility data Полный текст |
