Structural studies and magnetic properties of Fe/Ag superlattices

Fe(110)/Ag(111) superlattices with Ag layer thicknesses of 30 or 60 Å and various Fe layer thicknesses have been fabricated by high-rate sputtering and studied by x-ray diffraction magnetometries, and Mössbauer spectroscopy. A slightly enhanced magnetic moment and hyperfine field, and a reduced Tc h...

Zusammenfassung:Fe(110)/Ag(111) superlattices with Ag layer thicknesses of 30 or 60 Å and various Fe layer thicknesses have been fabricated by high-rate sputtering and studied by x-ray diffraction magnetometries, and Mössbauer spectroscopy. A slightly enhanced magnetic moment and hyperfine field, and a reduced Tc have been observed in samples with thin Fe layers. The magnetization exhibits a BT3/2 dependence with very large values of B.
