ملخص: We have investigated the magnetic properties of semi-infinite systems of the ordered FeV in the CsCl structure. We use a self-consistent real-space tight-binding method in the unrestricted Hartree-Fock approximation to the Hubbard Hamiltonian. The magnetic moment at low-index surfaces (001) and (111) of perfectly ordered Fe0.5V0.5 depends dramatically on the chemical component present at the surface. When Fe is at the surface, magnetic moments of 1.5[mu]B are obtained. The (110) structure contains both Fe and V and its magnetization is smaller.
