Local magnetic-switching-behaviour of Magnetic Tunnel Transistors studied by Ballistic Electron Magnetic Microscopy (BEMM) — •Emanuel Heindl, Johann Vancea, and Christian Back —
Institut für Experimentelle und Angewandte Physik, Universität Regensburg, Universitätsstr. 31, 93053 Regensburg

We used Ballistic Electron Magnetic Microscopy to study the local magnetic properties of spin-valve-structures. Local switching behaviour has been measured for Py/Cu/Co- and FeCo/Au/FeCo-spin-valves with magnetoresistance-effects of several hundred percent. Close to the switching field µm-scale-magnetic-domains have been imaged.
