Formation of localized magnetic states in a metallic host is a classic problem of condensed matter physics formalized by P. W. Anderson within the so called single impurity Anderson model (SIAM). The general picture in a host of a simple one-band metal is that a large Hubbard U in the impurity orbital is pre-requisite for the formation of localized magnetic states. In recent years three dimensional (3D) Dirac solids have emerged the hallmark of which is strong spin-orbit interaction. In this work we show that such a strong spin-orbit interaction allows to form localized magnetic states even with small values of Hubbard U. This opens up the fascinating possibility of forming magnetic states with s or p orbital impurities - different from traditional paradigms of d or f orbital based magnetic moments.
