Study of Hyperfine Field Data on Actinide Impurities in3dFerromagnetic Hosts

Abstract
Hyperfine-field data on actinide impurities in ferromagnetic transition hosts are analyzed in terms of conduction-electron polarization and d-electron contributions, except for Np, Pu, and Cm. For these special impurities, it is necessary to invoke the hyperfine-field contribution due to magnetic localized 5f shells.
