Tuesday, March 9, 2004, 15:00–19:00, Bereich A

Magnetic characterization of monodispersed and oxide-coated Fe cluster assemblies — •O. Michele1, J. Hesse1, H. Bremers1, D.L. Peng2, K. Sumiyama2, T. Hihara2, S. Yamamuro2, H. Ahlers3, and K. Weyand31Institut für Metallphysik und Nukleare Festkörperphysik, TU Braunschweig, Mendelssohnstr. 3, 38106 Braunschweig, Germany — 2Department of Materials Science and Engineering, Nagoya Institute of Technology, Nagoya 466-8555, Japan — 3Physikalisch-Technische Bundesanstalt, Bundesallee 100, 38116 Braunschweig, Germany

Monodispersed and oxide-coated Fe cluster assemblies were prepared using a plasma-gas-condensation style cluster beam deposition apparatus. The characterization of four different samples is presented using electron microscopy and SQUID magnetometry. The evaluation is based on the preparation of different low temperature magnetic states of the samples and measuring its magnetization depending on temperature.
