Hyperfine Fields on Actinide Impurities in Ferromagnetic Fe and Ni Hosts

摘要

We discuss the local magnetic moments and magnetic hyperfine fields on actinide impurities diluted in Fe and Ni hosts. One adopts a Anderson–Moriya model in which a localized 5f level is hybridized with a spin polarized and charge perturbed d-conduction band. Our self-consistent numerical calculations for the hyperfine fields on the impurity sites are in good agreement with the available experimental data.
