Local Correlation Physics of Transition Metal Atoms on Noble Metal Surfaces — •M. Alexander Schneider — Lehrstuhl für Festkörperphysik, Universität Erlangen, Staudtstr. 7, D-91058 Erlangen

Scanning tunneling spectroscopy at low temperatures has allowed experimentalists to access the properties of the single Kondo impurity at surfaces [1]. This local approach proved fruitful as it has opened the route to study systematically the coupling of an impurity to various electronic states at the surface [2] and also the coupling between Kondo impurities [3]. In my talk I will discuss the experimental findings of the properties of Co-Atoms on noble metal surfaces and multilayer substrates.
