Oxygen-Induced Magnetism of the Nonreconstructed Chromium (100) Surface

Abstract
With use of the technique of spin-polarized photoemission the magnetic properties of the chromium (100) surface have been investigated. Highly diluted oxygen incorporated into the lattice induces magnetic long-range order whereas oxygen adsorbed on top of the surface does not. No indication of ferromagnetism of the oxygen-free surface has been observed.
