使用数值模拟技术研究了通过直接传递积分耦合的金属中两种磁性杂质之间的磁相互作用的性质。研究发现，杂质从未表现出铁磁相关性，这证实了 Gottlieb 和 Suhl 的微扰理论计算结果，并且与其他研究相矛盾。当局域能级接近费米能级时，均匀自旋和交错电荷磁化率占主导地位。讨论了这些发现的后果。
The nature of the magnetic interaction between two magnetic impurities in a metal that are coupled through a direct transfer integral is studied using a numerical-simulation technique. It is found that the impurities never display ferromagnetic correlations, confirming the results of a perturbation-theoretic calculation by Gottlieb and Suhl and in contradiction with other studies. The uniform spin and staggered charge susceptibilities dominate as the localized level approaches the Fermi level. The consequences of these findings are discussed.
