The vanadium magnetic
polarization in NdFe12-xVx and Fe1-xVx intermetallic compounds has been studied by X-ray
magnetic circular dichroism. For all the compounds it was found that the
vanadium moment is always antiferromagnetically coupled with the iron moment
and reaches the value of 1 mB for systems with
low vanadium concentration. A theoretical KKR-CPA study of hyperfine fields in
Fe1-xVx revealed the induced character of the vanadium
polarization.
