摘要：
Mossbauer spectroscopy with Eu-151 nuclei was applied to study magnetic properties of Fe/Eu multilayers as a function of the Eu layer thickness. The Mossbauer spectra at 4.2 K for [Fe(40 angstrom)/Eu(x angstrom)] with x=70, 100, and 200 consist of two magnetic components: a major component with hyperfine parameters close to those of bulk Eu metal and an additional component with a smaller hyperfine field. The latter component is attributed to Eu at the interface region. The spectrum at 4.2 K for [Fe(40 angstrom)/Eu(30 angstrom)] has only a component with a reduced hyperfine field, indicating that the Eu layers lose the bulk magnetic properties.
