Spintronics is a generalization of electronics: Electronics means charge carrier transport, spintronics adds to this transport the supplementary degree of freedom spin which has been neglected since the roots of electronics. In this sense, spintronics is opening a new dimension of functional devices which is even more mighty than it may look at a first glance: The electron spin and its orientation is a pure quantum mechanical phenomenon which leads in its complexity to much more information coding depth and combinatorial operations than the storage and transport of charges in classical electronics. That is why the quantum bit (qubit) concept has been introduced by Schumacher [1].

All authors gratefully acknowledge the fruitful cooperation under the direction of Hartmut Zabel within the SFB491 and the financial support via the DFG. We appreciated the collaboration with Ellen Schuster, Frank Stromberg, Heiko Wende and Werner Keune from the Universität Duisburg-Essen for fruitful discussions and regarding the growth of the ferromagnetic metal structures with perpendicular anisotropy, Dirk Reuter for his expert help in MBE, Astrid Ludwig, Nicole Stracke and Nadine Viteritti for expert sample preparation. We gratefully acknowledge the expert experimental assistance of Jie Huang and Sven Eliasson. We acknowledge financial support by the RUB Research School, the DFH/UFA DFDK-05-06, the SPP 1285, and the BMBF QuaHL-Rep 01BQ1035.
