摘要：

An oscillatory interlayer coupling in Co/Au(111)/Co has been obtained from polar Kerr hysteresis loop measurements on a molecular-beam-epitaxy-grown 50 angstrom Au/2 angstrom Co/0-40 angstrom Au wedge/7 angstrom Co/20 angstrom Au sample deposited on a Cu(111) single crystal. The period of the coupling is seen to increase from 11 to 14 angstrom with increasing Au thickness, indicating a preasymptotic behavior. The asymptotic period of 14 +/- 1 angstrom is larger than the theoretically expected period of 11.4 angstrom. The observation of coupling up to 40 angstrom Au will be discussed in relation to the general absence of coupling in evaporated Co/Cu(111)/Co samples.
