我们重新审视的问题的自发磁化的杂质原子在一个简单的金属主机。主要特征是：（i）在杂质周围形成球形自旋密度/电荷密度波;（ii）与顺磁态相比，自旋极化态下的赝原子尺寸显著减小，（iii）孤立原子的电子亲合势与自旋极化的相关性，这是通过追踪在包封电子气的低密度极限中伪原子到孤立负离子的转变来阐明的。
We revisit the problem of the spontaneous magnetization of an {\em sp} impurity atom in a simple metal host. The main features of interest are: (i) Formation of the spherical spin density/charge density wave around the impurity; (ii) 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.
