Abstract
The conduction electrons' contribution to the hyperfine field at a nuclear site in a ferromagnetic alloy of transition metals arises from direct exchange polarization and from hybridization of the conduction electrons wavefunction with the d orbitals of the magnetic atoms. Within a simple model, it is shown that, at an impurity site, these two contributions are of the same order of magnitude and that the resulting net polarization amounts to a few tenths of a Bohr magneton. A quantitative agreement with hyperfine field measurements, would require a deeper selfconsistent analysis of the conduction electrons scattering.Keywords
