Abstract
A tight-binding type self-consistent band calculation is used to study the local magnetic moments of the ordered FeV alloy with CsCl-type crystal structure within the Hartree-Fock approximation of the Hubbard model for the spin polarisation. It is shown that the reasonable choice of the parameters for the numbers of d-electrons and intra-atomic Coulomb integrals can account for the experimental values of the local moments if the hopping integrals between Fe and V are chosen to be about 6% smaller than the usual geometrical average of the hopping integrals for pure metals.
