研究了用机械可控断裂结(McBj)技术制备的钴(Co)纳米触头的电导，以了解铁磁原子尺寸触头中Fano共振的起源。在原子尺度的接触中，零偏压反常用Fano公式很好地拟合。引入特征温度作为公式的拟合参数，其分布符合对数正态分布。这表明该异常可能是由近藤效应引起的。此外，在需要保持体铁磁性的大尺寸接触中观察到零偏压反常现象。这表明近藤效应和铁磁性共存。
The electrical conductance of cobalt (Co) nano-scale contacts prepared by a Mechanically Controllable Break Junction (MCBJ) technique has been studied to understand the origin of Fano resonance in ferromagnetic atomic-sized contacts. In an atomic-scale contacts, the zero-bias anomaly is well-fitted by the Fano formula. The characteristic temperature, which is introduced as the fitting parameter of that formula, exhibits the log-normal distribution. These indicate that the anomaly is likely caused by Kondo effect. Moreover, the zero-bias anomaly is observed in large scale contacts where the bulk ferromagnetic properties should be retained. This suggests the coexistence of Kondo effect and ferromagnetism.
