Abstract / Full Text

The paper presents the research results of the temperature dependence of molar heat capacity at a constant pressure within the temperature range from 5 to 300 K for vanadium-based materials. The density of states is calculated for all the materials near the Fermi level. It is shown that for V3Si and V3Ge compounds the density of states correlates with the superconducting transition temperature. It is also found that the metal-insulator transition temperature lowers with increasing density of states in V2O3 and V1.973Me0.027O3 (Me – Al, Fe, Cr) compounds.
