Fermi Surfaces in NbcMo1−c Random Alloys

Abstract

Within the KKR‐CPA framework the Bloch spectral function of some Nb_cMo_1−c alloys are computed. By looking at the results for E = E_F the topology of the Fermi surface is studied as function of concentration. The results are in agreement with experimental indications given by the measurements on elastic constants in such alloys. The calculations confirm that a rigid band model for these systems can explain the observed properties at the Fermi level.
