SPIN-RESOLVED INVERSE-PHOTOEMISSION FROM PT FE(001)/

The magnetic properties of unoccupied electronic states of Pt films gr own on Fe(001) have been investigated by means of spin-resolved invers e photoemission. Interface and overlayer derived states are clearly id entified, while their polarization dependence indicates a ferromagneti c coupling between Pt and Fe. The magnetic moment induced in the film remains, however, confined at the interface and polarization effects d isappear above similar to 5 Pt atomic layers. The persistence of inter face derived states in thicker films points towards the formation of a nonabrupt interface.
