Magnetic properties of thin chromium Layers in Gd/Cr and Y/Cr multilayers studied using /sup 119/Sn Mo/spl uml/ssbauer spectroscopy

Magnetism of Cr layers in Cr/Sn/Cr/Gd and Cr/Sn/Cr/Y multilayers with monatomic Sn layers grown on polyimide substrates has been studied using /sup 119/Sn Mo/spl uml/ssbauer spectroscopy. The results are quite different from those for Cr/Sn multilayers without the rare-earth metals. It is suggested that the Gd and Y layers have a strong effect that makes neighboring Cr nonmagnetic.
