SURFACE MAGNETISM AND ELECTRONIC-STRUCTURE OF ULTRATHIN FCC FE FILMS

Spin- and angle-resolved photoemission show that a very similar develo pment of the electronic structure occurs in fee Fe films grown on Co(1 00) and on Cu(100). On both substrates the electronic structure displa ys distinct changes as a function of the thickness which correlate wit h the magnetic properties of the film. The measurement of the photoele ctron spin polarization demonstrates that the surface region of Fe fil ms on Co(100) as well as on Cu(100) is magnetically alive at all thick nesses.
