The temperature dependence of the hyperfine field at Fe atoms was determined by Mössbauer and continuous-wave NMR methods for Fe-based alloys containing Ti, V, Cr, Mn, Co, and Ni impurities. A marked anomaly was found in the case of Mn, and a lesser one for Ni. The temperature anomaly of the hyperfine field at iron atoms in the neighborhood of Mn impurities can be described with a linear combination of two terms, one proportional to μFe, the other to μMn-μFe. We suggest that the latter is brought about by the conduction-electron polarization.
