SP6: Scanning tunneling microscopy and spectroscopy of magnetic molecules

An indispensable tool for studying single molecule magnets as the fundamental functional building blocks for future molecular spintronic devices is (spin-polarized) scanning tunneling microscopy and -spectroscopy (SP-) STM/STS. This method provides unique insight into the electronic and magnetic properties of molecular magnet systems. In this project we will use (SP-) STM/STS for the investigation of single molecular magnets adsorbed on well defined crystalline substrates, ordered aggregates, self-assembled monolayers and multilayer systems. Crucial aspects for the bottom-up development of molecular spintronic devices will be studied. These include the understanding of adsorption geometries, electronic charge transfer mechanisms, intra- and intermolecular magnetic exchange coupling mechanisms, the interaction of the molecular spin with the substrate and the tip, and in particular, the spin-dependent tunneling transport (magnetotransport) properties of the molecules.
