The vanadium magnetic polarization in NdFe_12-xV_x and Fe_1-xV_x 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 m_B for systems with low vanadium concentration. A theoretical KKR-CPA study of hyperfine fields in Fe_1-xV_x revealed the induced character of the vanadium polarization.
