Polarised neutron study of iron-vanadium alloys

Abstract

The authors have made polarised neutron diffuse-scattering measurements on ferromagnetic alloys Fe1-cV/sub /c(0.01<c<0.2). The nuclear magnetic cross sections are analysed within Marshall's formalism, using the short-range order parameters previously measured. These new results show a negative constant moment of about -1 mu B on vanadium sites up to 10 at.% V. In particular they observe no steep enhancement of the vanadium moment at dilute concentrations. The iron and vanadium moments are in good agreement with theoretical predictions.
