Abstract
Fe/V multilayers prepared by sputtering has been studied by conversion electron Mössbauer spectroscopy. An extended series of samples of the Fe( x)/V( y) system has been studied both at room temperature and at 10 K. The series consisted of samples with x=3 ML (monolayers), 5 ML, 7 ML, 10 ML and 20 ML and y=5 ML, 10 ML and 14 ML. The obtained hyperfine field distributions point to quite diffuse interfaces, where multilayers with Fe layer thickness less than 5 ML are mainly non-magnetic. The influence of the spacer layer thickness on the Fe hyperfine field has also been investigated. The results indicate that interlayer coupling may influence the hyperfine field distribution positively.
