Magnetic and Nonmagnetic Metal Nanostructures

01.01.2007 - 01.12.2009
Forschungsförderungsprojekt
This Project is based on our expertise in determining crystallographic structures and chemical composition of surfaces on the atomic level by high resolution STM supported by standard techniques like quantitative LEED, LEIS, AES and XPS. A specific system, ultrathin films of Fe on Cu(100) will be the starting point for a new type of magnetic nanostructures. In this system the phase transition from nonmagnetic fcc Fe into ferromagnetic bcc Fe can be induced by ion beams. Furthermore magnetic clusters on nonmagnetic templates (stepped or adsorbate induced nanostructures) will be grown and beside the crystallographic, also the magnetic structure will be studied. On the other hand alloy clusters grown on low index and vicinal oxide surfaces will be studied as model systems in heterogenous catalysis. The goal will be to determine the chemical composition and crystallographic structure of clusters as well as the adsorption of small molecules on this clusters. The main goal of the project will be how the the chemical, magnetic, electronic and crystallographic structure is influences by the form and size of the metallic clusters.
