摘要：

We prepared Nb/Fe multilayers with varying Nb or Fe thickness by means of MBE. The x-ray diffraction patterns show good layering quality. Critical field measurements as a function of temperature and angle demonstrate that very thin Fe layers (approximate to 12 angstrom) decouple the Nb layers completely thus leading to 2D behaviour of the multilayers. The dependence of T-c as a function of Nb thickness and the critical fields are well described by the theoretical model derived for the proximity effect in superconductor/ferromagnet multilayers.
