本文综述了利用自旋分辨扫描隧道光谱（SP-STS）对吸附在非磁性固体表面的原子（adatoms）进行磁成像研究的最新进展。使用磁稳定自旋极化尖端的磁场依赖光谱学已经被推动到能够在单原子自旋极限上进行磁强计。以铂（1111）上Co原子为例，对该技术进行了详细的综述。我们讨论的问题有关的基本磁性的个别adatoms以及有关他们的底物介导的相互作用已经解决。
This review focuses on recent advances in the magnetic imaging of atoms adsorbed on a nonmagnetic solid surface (adatoms) by means of spin-resolved scanning tunnelling spectroscopy (SP-STS). Magnetic field dependent spectroscopy using magnetically stable spin-polarized tips has been pushed to enable magnetometry on the single atomic-spin limit. We give a detailed review of the technique for the example of Co adatoms on Pt(1 1 1). We discuss the issues concerning the basic magnetic properties of individual adatoms as well as concerning their substrate mediated interactions that have been addressed.
