小磁簇磁矩的实验结果和理论结果之间的差异被归因于轨道磁力的贡献。在这封信中，我们表明具有大轨道磁矩的磁态并不总是在能量上有利；然而，它们可以通过涂覆簇或将其沉积在适当的基底上来实现。更重要的是，我们的工作表明，决定团簇磁性的关键因素是团簇组成原子的内在特性，因此也是团簇组成原子的外在特性。
The discrepancy seen in the experimental and theoretical results on the magnetic moment of a small magnetic cluster has been attributed to the contribution arising from orbital magnetism. In this Letter we show that the magnetic states with large orbital magnetic moment are not always energetically favorable; they could, however, be realizable by coating the cluster or deposing it on appropriate substrates. More importantly, our work shows that the crucial factors that determine the cluster magnetism are found to be the intrinsic, and consequently, the extrinsic properties of the constituent atoms of the cluster.
