摘要：

The structure and the interlayer exchange coupling in MBE-grown nominal Fe/Ge1-xFex/Fe (x = 0.0, 0.25, 0.33, 0.5) and Fe/Si/Fe sandwiches with wedge-shaped spacer layers were investigated. In the case of Fe/Si a sample with a wedge-shaped magnetic layer was also studied. From a structural analysis with LEED and from a magnetic analysis with the magneto-optical Kerr effect, it is concluded that the Si spacer transforms into an SiFe alloy with the deposition of Fe. A strong antiferromagnetic coupling is found in the case of Fe/Si, but no antiferromagnetic coupling is found for Fe/Ge1-xFex It appears that the coupling behavior in Fe/Si(SiFe)/Fe sandwiches as a function of spacer thickness is monotonous rather than oscillatory.
