摘要：

The electronic structure of Cu films on Co(100) in the k-space region associated with the short-period oscillation of the interlayer coupling in Cu/Co(100) multilayers has been examined by spin-and angle-resolved photoemission and by ab initio calculations. The photoemission intensity near the Fermi energy exhibits a rapid oscillatory behavior as a function of film thickness with a period close to that of the interlayer exchange coupling. The photoemission intensity and polarization reflect a modulation of the density of states induced by spin-polarized quantum-well states, in good agreement with ab initio calculations of quantum-well states.
