Layer-resolved magnetic moments for Fe in a Co/Fe (001) superlattice

From the Mossbauer spectrum of a high-quality Fe/Co superlattice, the inter face quality was ascertained by comparison of the details of the spectrum w ith the published value of the magnetic hyperfine held for iron in cobalt a nd no detectable roughness/intermixing was found. From the variation of the iron magnetic hyperfine field as a function of location of the iron atoms, with respect to the interface, the individual iron magnetic moments could be derived. The magnitude of the magnetic moments thus obtained correlate w ell with recently calculated values. (C) 2001 Elsevier Science B.V. All rig hts reserved.
