摘要：

Recently, the magnetic properties of chromium in Fe/Cr multilayers were studied with Mossbauer spectroscopy by inserting a tin monolayer in the chromium. Complementary neutron-diffraction studies on Fe/Cr(t) and Fe/Cr(t/2)/Sn(2(angstrom)/Cr(t/2) multilayers with t-80 and 160 angstrom are presented here. The Fe/Cr multilayers behave as previously observed, however the samples with tin deviate from these trends. These deviations are more prominent in the Fe/Cr/Sn/Cr multilayer with t = 80 angstrom. Instead of an incommensurate to commensurate spin-density-wave (SDW) transition with increasing temperature (T) as seen without tin, a dominant commensurate component is observed at low T transforming to an incommensurate phase at higher T. The general SDW behaviour of chromium in Fe/Cr multilayers seems to be changed significantly by the insertion of Sn, allowing the tailoring of magnetic properties of Fe/Cr systems in a new way.
