The charge states of single molecular magnetic chains were manipulated with a scanning tunneling microscope and identified by spin-flip inelastic tunneling spectroscopy. We show that the charged and neutral states have different spin structures and therefore exhibit different features associated with the spin-flip processes in tunneling spectra. The experiment demonstrates a general approach for detecting the charge states at the nanometer scale in a more straightforward manner than using indirect information.
单分子磁链的电荷态可以通过扫描隧道显微镜进行操纵，并通过自旋翻转非弹性隧道谱来识别。我们表明，带电和中性状态具有不同的自旋结构，因此在隧道谱中表现出与自旋翻转过程相关的不同特征。该实验证明了一种在纳米尺度上以比使用间接信息更直接的方式检测电荷态的通用方法。
