Electronic structure of transition metal diborides

Electronic specific heat, magnetic susceptibility and V 51 Knight shift measurements on the transition metal diborides of the first series (ScMn) show that the values of the density of states at the Fermi level are high and typical for a dominantly d-character band. Very high values of the density...

Description
Summary:Electronic specific heat, magnetic susceptibility and V 51 Knight shift measurements on the transition metal diborides of the first series (ScMn) show that the values of the density of states at the Fermi level are high and typical for a dominantly d-character band. Very high values of the density of states for CrB 2, (VCr)B 2 and (MnCr)B 2 are related to strong electron-electron correlation effects. Des mesures de chaleur spécifique électronique, de susceptibilité magnétique et de déplacement de Knight sur les diborures de la lère série de transition (Sc à Mn) montrent que la densité d'états au niveau de Fermi a des valeurs typiques de bandes à caractère dominant d. Les très fortes valeurs de la densité d'états pour CrB 2, (VCr)B 2 et (MnCr)B 2 sont dues à des effets de corrélation électron-électron.
