Abstract

Magnetization induced second harmonic generation is used to investigate the magnetic behavior of fcc Co films growing on Cu(001). An oscillatory behavior of the magnetic asymmetry with one monolayer period is observed. At half filled layers the magnetic signal originating from the surface of the film is enhanced with respect to filled layers. The relation of these results to the magnitude of the magnetic moments of Co atoms at step edges is discussed.
