自由钴和铁团簇的双稳态
Bistability of Free Cobalt and Iron Clusters
摘要：
用低温分子束测量了钴和铁团簇CoN，FeN（20 < N < 150）的基态磁矩μN/N2 μB，亚稳态激发态μN */N μB（铁团簇为μN ~ 3 N μB和μN* NμB）。这两个国家之间的能隙消失的大集群，这解释了快速收敛的磁矩的整体价值，并建议，基态的散装涉及的叠加的两个，符合波动的本地订单在散装巡回铁磁性。
英文摘要：
The cobalt and iron clusters CoN, FeN (20 < N < 150) measured in a cryogenic molecular beam are found to be bistable with magnetic moments per atom both μN/N 2μB in the ground states and μN */N μB in the metastable excited states (for iron clusters, μN ~3NμB and μN* NμB). This energy gap between the two states vanish for large clusters, which explains the rapid convergence of the magnetic moments to the bulk value and suggests that ground state for the bulk involves a superposition of the two, in line with the fluctuating local orders in the bulk itinerant ferromagnetism.
