Abstract

We revisit the problem of the spontaneous magnetization of an sp impurity atom in a simple metal host. The main features of interest are as follows: (i) Formation of the spherical spin density and charge density wave around the impurity, (ii) a considerable decrease in the size of the pseudoatom in the spin-polarized state as compared with the paramagnetic one, and (iii) relevance of the electron affinity of the isolated atom to this spin polarization, which is clarified by tracing the transformation of the pseudoatom into an isolated negative ion in the low-density limit of the enveloping electron gas.
