摘要：
Self-consistent spin-polarized relativistic calculations of the electronic structure and magnetic characteristics of U, Np, Pu impurities in thorium have been carried out. It is shown that all these metals in thorium reveal well-defined magnetic behavior. The values of magnetic moment at the impurities are defined by the partial cancellation of spin and orbital contributions. For Pu the total moment is large and of orbital nature, the magnetic moments of U and Np are small and have spin origin.
