M. Donath, SPIN-DEPENDENT ELECTRONIC-STRUCTURE AT MAGNETIC-SURFACES - THE LOW-MILLER-INDEX SURFACES OF NICKEL, Surface science reports, 20(5-6), 1994, pp. 251-316
The understanding, on a microscopic level, of magnetic phenomena at su
rfaces and interfaces hinges on a detailed knowledge of the spin-depen
dent electronic structure, particularly close to the Fermi level. Expe
rimentally, the most direct access to the spin-dependent electronic st
ates is given by angle-resolved photoemission and inverse photoemissio
n with spin resolution for the emitted and incident electrons, respect
ively, This report reviews spin-resolved inverse photoemission results
on empty electronic states at the low-Miller-index surfaces of nickel
as a prototype of a ferromagnetic 3d transition metal. Examples cover
bulk-like electronic states, different kinds of Surface states, and a
dsorbate-induced modifications of the surface electronic structure. Th
e data are discussed along with photoemission results on the occupied
states. A variety of results is presented which demonstrate how surfac
e magnetic properties are reflected in the spin-dependent electronic s
tructure.
