Abstract
Angle-resolved-photoemission studies of the dispersion of the quantum- well states in copper thin films deposited on a Co(001) substrate reve al that hybridization in the interface leads to a large increase in th e effective mass of the electrons. These observations have implication s for theories of the oscillatory exchange coupling in the related mag netic multilayers, particularly where Fermi-surface spanning vectors a way from the center of the zone are invoked as in the case of the shor t-period oscillation in the Co/Cu(001) multilayers.
