An apparatus for the synthesis of cluster-based materials — •Arne Fischer, Robert Kruk, and Horst Hahn — Karlsruher Institut für Technologie, Institut für Nanotechnologie, 76344 Eggenstein-Leopoldshafen, Germany

A cluster deposition system for the synthesis of materials composed of mass-selected clusters embedded in various matrices as well as cluster-decorated surfaces was constructed and first deposition experiments were performed.

The system covers a large range of cluster sizes from single atoms up to clusters consisting of several thousands of atoms and provides a cluster beam with a narrow size distribution. Offering the ability to co-deposit matrix materials and mass selected clusters in well-defined ratios the system allows for studying material properties as a function of cluster size and density in the matrix. Hence this approach can open pathways to a new class of materials with tailored electronic, magnetic or catalytic properties.

In recent experiments the exchange bias was studied in thin films composed of ferromagnetic clusters and antiferromagnetic matrix materials.
