Abstract

A highly precise local spin density (LSD) study of Fe(110) surface (investigated by Korecki and Gradmann using in situ conversion-electron Mössbauer spectroscopy, CEMS) predicts a 20% enhancement of the surface magnetic moment over bulk; the absence of a Friedel oscillation of the moment into the bulk region but the presence of an oscillatory behavior for the magnetic hyperfine field, H_c; a magnetically induced contribution to the isomer shift; and a large electric field gradient only at the surface layer.
