Multilayered metal films with artificial superstructures are prepared by alternate deposition of two elements in ultrahigh vacuum. Preparation and characterization for Fe-Mg and Fe-V superlattices are described. From hyperfine field measurements, chemical profiles of interfaces are discussed. Magnetic properties of extremely thin Fe layers sandwiched in between Mg layers are studied by means of Mőssbauer absorption spectroscopy.

- /21/.A sample of Fe monomers dispersed in Mg matrix was prepared by co-deposition of Fe(0.5%) and Mg(99.5%). The Mőssbauer spectrum has no hyperfine structure even at 0.1K. An external field of 45k0e does not induce a hyperfine field (at 4.2K). These results indicate that an Fe impurity in Mg has no local magnetic moment. If Fe atoms happen to diffuse into Mg layers, the Mőssbauer spectrum should show a non-magnetic fraction. The result on Fe monomers in Mg will be published elsewhere; K. Kawaguchi, R. Yamamoto, N. Hosoito and T. Shinjo, in preparation.Google Scholar
