Abstract

Ultrahigh-quality thin fct-Co films grown on Cu(001) have been investigated by 59Co nuclear magnetic resonance. The influence of the spin-dependent electron scattering at the interfaces is observed for at least four Co atomic layers from the interface with monolayer resolution. An oscillatory effect on the Co hyperfine field with a period of several monolayers is measured, corresponding to the oscillating conduction electron polarization. The observation is exclusively possible in this system due to its very narrow resonance lines, corresponding to a virtually perfect Co structure.
