Abstract
The results of a comparative study of low-temperature heat capacity and resistivity of weakly nonstoichiometric Fe–V–Al alloys with their composition varied (in iron, vanadium, and aluminum atoms individually) with respect to the stoichiometric Fe2Val alloy are reported. The electron density of states near the Fermi energy is estimated for the studied alloys. The data confirming the presence of a narrow pseudogap at the Fermi level in alloys enriched with vanadium and the lack of such a pseudogap in alloys enriched with iron or aluminum are obtained.
