The electronic structure of the pseudobinary cubic Laves phase (C15) H
f1-xZrxV2 alloys is presented. The self-consistent band calculations a
re made by the tight-binding LMTO method. The calculated density of st
ates at the Fermi level reaches a maximum at x = 0.35. The experiments
indicated that the electronic specific heat coefficient and the susce
ptibility have a maximum at the same concentration of zirconium.
