将Abrikosov-Gorkov超导体稀磁杂质对破裂理论推广到磁性离子浓度较大或在规则晶格上的情况。详细讨论了磁性离子向反铁磁相转变的情况。详细讨论了由于反铁磁相变附近关联范围的增大以及电子在反铁磁相中对自旋波的非弹性散射，在Abbrikosov-Gorkov值范围内增加或减小对破裂的物理考虑。最近的实验结果是根据新的理论来考虑的。
The Abrikosov-Gorkov theory for pairbreaking in superconductors due to a dilute concentration of magnetic impurities is generalized to the case when the magnetic ions are present in a large concentration or on a regular lattice. The case in which the magnetic ions undergo a transition to an antiferromagnetic phase is considered in detail. The physical considerations for increased or decreased pairbreaking over the Abbrikosov-Gorkov value due to the increased range of correlations near the antiferromagnetic transition and due to inelastic scattering of electrons off spin waves in the antiferromagnetic phase are discussed in detail. Recent experimental results are considered in terms of the new theory.
