Abstract
We report a combined photoemission and inverse-photoemission study of the quantum-well states formed in copper thin films deposited on a fcc Co(001) substrate. In particular, we examine the k point that would correspond to the Fermi-surface crossing that would allow the quantum-well states to mediate the short period of exchange coupling in the associated magnetic multilayers. The states do not display a strong intensity in photoemission, an effect that we attribute to interfacial roughness. © 1996 The American Physical Society.
