摘要
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.
