摘要：
The exchange coupling of Fe across Cr oscillates as a function of the Cr-thickness with a short and a long period. The short-period oscillations are only observed in samples with very good quality. In addition to ferro- and antiferromagnetic type coupling there is also a contribution favouring a perpendicular magnetization alignment of neighbouring magnetic films. Similar effects as for the Fe/Cr system we find also for Fe/Au and Fe/Al. For the Fe/Ag system AF type coupling could not be established. The effect of the various types of coupling on magnetic domains has been studied in the Fe/Cr system. An analysis of the new magnetoresistance effect due to antiparallel alignment revealed that for the Fe/Cr system it is due to a spindependent electron scattering at the Fe-Cr interfaces. Values for the scattering rates have been obtained.
