Shot noise of contacts to Fe atoms and FeH_n on Au(111) — •Michael Mohr, Andreas Burtzlaff, Alexander Weismann, and Richard Berndt — Institut für Experimentelle und Angewandte Physik, Christian-Albrechts-Universität zu Kiel, 24098 Kiel

The ballistic transport through contacts to single Fe atoms on Au(111) surfaces is investigated with a 4 K scanning tunneling microscope. The shot noise of the current is measured to obtain information about its spin polarization. The influences of other Fe atoms close to the contact and of hydrogen in the contact are addressed
