Theoretical spin- and angle-resolved photoemission spectra from Fe(110)

Abstract

Spin- and angle-resolved photoemission spectra of ferromagnetic Fe(110) for various initial-state symmetries have been calculated by means of a nonrelativistic one-step model Green’s-function formalism and potentials for surface and subsurface layers obtained from a highly precise local-spin-density film calculation. Comparison with experimental data shows very good agreement concerning binding energies and previous interpretations. Most features can be understood in terms of direct transitions in the bulk band structure; two are identified as surface states.
