摘要：

Evidence of the existence and distribution of an induced spin polarization of the conduction electrons in the Cu layers of Fe/Cu multilayers has been obtained by nuclear magnetic resonance (NMR). Fine structure associated with the spin-echo signal of Cu-63 and Cu-65 nuclei shows that the spin polarization and an associated exchange field oscillate in sign, similar to the characteristics of the RKKY interaction. However, an accurate determination of the period of the oscillations cannot be determined solely from the NMR data at the present time.
