| Abstract: | We study, within the Bethe lattice approximation, the electronic structure of the ordered, disordered and hydrogenated intermetallic Pd3Fe. We employ a simple one-orbital per site model hamiltonian, which includes a Hubbard-like Coulomb interaction term. This is treated in the Hartree-Fock approximation. We present results for the number of electrons, magnetic moments, and density of states at the Fermi level. Good agreement with available experimental data is obtained. |
