It is shown that magnetization-induced second harmonic generation (SHG
) is a powerful tool for investigating surfaces and buried interfaces.
The source of the SHG is bound to the interface within a region of le
ss than 2 monolayers. Changes in the electronic structure of the Co an
d especially the Cu-covered Co films as a function of the Co/Cu film t
hickness are observed.
