考虑了原子团簇和磁团簇共存对电阻率的影响。结果表明，在Cu-Ni合金中，这种聚类会产生竞争效应，而在镍含量超过25%的合金中，原子聚类起主导作用，而在低镍含量合金中，磁聚类起主导作用。结果表明，在含镍量大于25%的合金中，电阻率随聚类的增加而减小，而在含镍量较低的合金中，电阻率随聚类的增加而增大。这种行为的变化是由于富镍团簇的磁矩对组成和团簇程度的非线性依赖，这是由于Ni原子的磁性状态对其邻近环境的依赖。
The effects of co-existing atomic and magnetic clustering on electrical resistivity are considered. It is shown that in Cu-Ni alloys such clustering produces competing effects and that while atomic clustering dominates the behaviour in alloys containing more than about 25% Ni, the magnetic clustering effects are predominant in lower Ni content alloys. The results in a resistivity which decreases with increased clustering in alloys with more than 25% Ni but which increases with clustering at lower Ni contents. This change in behaviour results from the non-linear dependence of the magnetic moments of the Ni-rich clusters upon composition and degree of clustering, which is due in turn to the dependence of the magnetic state of the Ni atoms upon their near-neighbour environment.
