The present research project "New Material for Magnetoelectronic Network" (Mag-El-Mat) is related to the new field of science and technology, called spin electronics. Investigations carried out within this subject are concentrated on the use of the electron spin degree of freedom as well as electronic charge. Possibility to make use of spin is of great importance, not only for cognitive reasons but also from the practical point of view, because the conventional silicon-based electronics is facing now barriers of fundamental nature, which hinder further miniaturisation. The main objectives of the present project are studies of electronic and magnetic properties of a vast class of nanoscopic materials, such as: thin films, multilayers, composites, molecular systems (including carbon nanotubes) and quantum dots.
