Spin-dependent empty electronic states at magnetic surfaces
Electronic states located with their wave functions at the surface of a three-dimensional ferromagnet or at the interface where two different materials meet, serve as a local probe where modified magnetic properties may occur. Exploring the spin dependence of these states is essential to developing a microscopic picture of magnetic phenomena at surfaces, in ultrathin films and in layered structures. Experimentally, the most direct access to the electronic structure is given by photoemission (PE) and inverse photoemission (IPE). This paper reports on spin polarised inverse photoemission (SPIPE) results concerning the spin-dependent empty electronic states at magnetic surfaces. Special attention is given to surface electronic states and changes of the spin-dependent electronic structure caused by adsorption of non-magnetic adatoms.
