摘要：

Epitaxial Cr/Sn multilayers composed of Cr(001) layers and very thin Sn layers were grown on MgO(001) substrates. The magnetic properties of the prepared multilayers were studied by Sn-119 Mossbauer spectroscopy. Magnetic hyperfine fields of 11 similar to 13 T, which are larger than the value reported for dissolved Sn sites in a Cr matrix, were found to he induced at the Sn nuclear sites of [Cr(t(Cr))/Sn(2 Angstrom)] multilayers (t(Cr) = 6, 10, 20, and 30 Angstrom) at room temperature. The result indicates that the magnetic ordering temperature of the Cr layers is much higher than the Neel temperature of hulk Cr (T-N = 311K). Possible magnetic structures in the Cr layers are inferred from the size and direction of the magnetic hyperfine field transferred at the Sn nuclear sites.
