摘要	Magnetic interlayer coupling between two Co layers across Cu/Ni-30/Cu-70/Cu(100) was investigated by the surface magneto-optic Kerr effect. The Ni30Cu70 layer at the center of the Cu layer was shown to shift the peak positions, rather than to change the strength, of the magnetic interlayer coupling. The density of states near the Fermi level was investigated by photoemission spectroscopy. We show that the peak-position shift in the magnetic interlayer coupling is associated with the quantum-well behavior in a symmetric double-quantum-well system. The phase accumulation model was applied to explain the results quantitatively.; Magnetic interlayer coupling between two Co layers across Cu/Ni-30/Cu-70/Cu(100) was investigated by the surface magneto-optic Kerr effect.
