Title: Simplified Theory Of The Surface Properties Of Semi-infinite Ferromagnetic Metals
Author: Rodrigues A.M.

Abstract: The surface magnetization and electron concentration are calculated for a tight-binding, single-orbital model of a transition metal in the Hartree-Fock approximation, for a (111) surface in the f.c.c. structure and a (100) surface in a s.c. one. Local Green's functions at the surface plane and in the bulk are expressed as continued fractions through the transfer matrix approach. Self-consistency plus constraints of local charge neutrality and equality of surface and bulk chemical potentials determine the surface intra-atomic Hubbard Us and chemical shift Δε of surface orbitals. The self-consistent equations were solved graphically by recourse to the integrated density of states for bulk or surface. The method is applied to systems with parameters adequate for Ni and Fe. © 1986 Società Italiana di Fisica.
