Collaborative Research Center 767
In January 2008 the new Collaborative Research Center 767 Controlled Nanosystems: Interaction and Interfacing to the Macroscale funded by the DFG has been established at the University of Konstanz. The initiative addresses the challenge of achieving a detailed understanding of the interaction of nanostructures, both among themselves and with their macroscopic environment. The common goal is always to precisely control and manipulate their properties in order to pave the way for new functionalities.
To this end, 14 projects in the fields of mechanical, optical, and electronic control of nanostructures are pursued by groups of the Physics and Chemistry departments of the University of Konstanz and of the MPI Solid State Research in Stuttgart. To promote young scientists in the SFB an integrated research training group has been established.
The spokesperson of the SFB 767 is Prof. Dr. Wolfgang Belzig from the Department of Physics of the University of Konstanz.

Nano Letters: The Quantum Magnetism of Individual Manganese-12-Acetate Molecular Magnets Anchored at Surfaces
Single molecular magnets (SMM) inspire the research in information storage, spintronics, and quantum computation due to their magnetic properties which lie at the interface between classical and quantum mechanical description. Manganese-12-Acetate (Mn12) is the archetypical SMM due to its high spin and long spin relaxation time. While these properties have been observed on bulk samples, the deposition on surfaces has not yet been possible while retaining these characteristics. In our experiment we demonstrate the surface deposition of intact Mn12 molecules by electrospray ion beam deposition. Using a scanning tunneling microscope we detect directly the preserved magnetism as low-energy fingerprint in inelastic spin-flip spectroscopy. These results are supported by DFT based calculations and establish that individual Mn12 molecules retain their intrinsic quantum magnetism.Steffen Kahle, Zhitao Deng, Nikola Malinowski, Charléne Tonnoir, Alicia Forment-Aliaga, Nicha Thontasen, Gordon Rinke, Duy Le, Volodymyr Turkowski, Talat S.
