To handicraft material systems with magnetic and semiconducting properties — •Safak Gök, Alexander Melnikov, Jun Ling Yang, and Andreas D. Wieck — Ruhr-Universität Bochum, Universitätstr. 150, D-44780 Bochum

We have tried to fabricate a material system, which owns semiconducting and magnetic properties at the same time. Therefore we have utilized the advantages of our combined molecular beam epitaxy - focused ion beam (MBE-FIB) -System, to deposite Mn atoms into GaAs in a soft landing mode. This technique offers the possibility to integrate the magnetic atoms into the semiconductor lattice with very low crystal defects. Magneto - transport measurements show an anomalous Hall effect which reveals clearly that our MBE-FIB-System makes possible an important progress the research towards convenient material for spintronics.
