Magnetic surface states on Fe(001)
- Physics Department, Brookhaven National Laboratory, Upton, New York 11973 (US)
The direct observation of magnetic surface states on Fe(001) is reported. A spin-polarized angle-resolved photoemission study identifies a minority surface resonance at {bar {Gamma}} (2.40-eV binding energy) and a minority surface state at {ital {bar X}} (2.25-eV binding energy) in the surface Brillouin zone. The majority counterpart of the minority surface resonance is not observed. Good agreement with 7- and 13-layer full-potential linearized-augmented-plane-wave calulations is found for the minority {bar {Gamma}} to {ital {bar X}} surface band. In addition, the 13-layer slab calculation is found to more correctly model the decay of the surface resonance into the bulk in contrast to the 7-layer slab where size effects play a role.
