摘要：

We examine the role of quantum well and interface states in mediating the coupling between magnetic films. We have studied with spin- and angle-resolved photoemission the electronic structure of Cu on Co(100) and Ag on Fe(100). Noble metal states of sp-derived character are found to be spin-polarized upon contact with the magnetic materials. In Cu films up to 10 monolayer thickness polarized states have been observed. These observations are well described within the framework of one-dimensional quantum-well states, for film thicknesses above a few monolayers. In the low coverage regime, the hybridization with the magnetic states of the substrate strongly influences the character and the dispersion of the conduction bands.
