Senior member of the INSTITUT UNIVERSITAIRE DE FRANCE
Jean-Pierre BUCHER is a professor at Université de Strasbourg (Unistra). He is head of the Research Group “Scanning probes for Nanomagnetism” at the IPCMS. J.P. Bucher received his PhD from the Ecole Polytechnique Fédérale de Lausanne (EPFL) for his study by spin-echo-NMR of quantum size effects and adsorbate induced modifications in Pt nanoclusters. In 1989 he was awarded a two year “Fellowship for Advanced Researcher” of the Swiss National Science Foundation to pursue research on molecular beams at University of Virginia in Charlottesville. There he built a Stern-Gerlach deflection experiment with a pulsed laser vaporization cluster source and time of flight mass spectrometer for the study of magnetic clusters. J.P. Bucher observed for the first time superparamagnetic relaxation in free cobalt clusters as well as the appearance of magnetic magic numbers in rare earth clusters of a few atoms. As an invited scientist at KFA-Jülich, Germany (1991), he worked in surface science and near field microscopy. In 1992 he spent 2 years as a research scientist at the EPFL, conducting UHV-STM studies of growth kinetics in heteroepitaxial metal systems and explored new ways of nanostructuring and self-organizing atoms on surfaces. In 1994 he got a position as a full professor at Université Louis Pasteur and became a group leader at IPCMS. J.P. Bucher possesses expertise in diverse fields of nanomagnetism, molecular nanoelectronics, spin electronics and development of instruments. In the last 10 years he focused his research on magnetotransport in STM junctions in the spin-polarized configuration (SP-STM). Atoms and molecules are addressed on an individual basis by near-field probes, with the main objective to accede specific magnetic properties and gain control over atomic scale quantum mechanical behavior of spin arrays. He is co-author of 130 publications in international reviews in the fields of magnetism of small object, atomic and molecular cluster physics, near field probes and instrumentation, surface science. He has directed and co-directed nineteen Ph.D. theses. He is senior member of the Institut Universitaire de France and holder of the reward of scientific excellence.
