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.
