Hyperfine Field Distributions in Fe/V multilayers

Abstract

Fe(x)/V(y) multilayers prepared by sputtering have been studied by Conversion Electron Mossbauer Spectroscopy both at room temperature and at 10 K. The series consisted of samples with x=3, 5, 7, 10 and 20 monolayers (ML) and y=5, 10 and 14 ML. The obtained hyperfine field distributions point to quite diffuse interfaces, where multilayers with nominal Fe layer thickness less than 5 ML are mainly non-magnetic. The results indicate furthermore that interlayer coupling may influence the Fe hyperfine field distribution positively.
