Following the official name of our department, we focus on possibilities to exploit the spin of electrons in novel electronical devices (spintronics) whose dimensions often scale down to sub-micron range (nanoelectronics). An archetypal material for corresponding studies is the dilute magnetic semiconductor (Ga,Mn)As and currently our interest shifts more to systems with metallic ferromagnets and antiferromagnets. We investigate these both experimentally and theoretically and occasionally spend also some effort on similar systems where spin does not play a major role. Our current research subjects include

• magnetic and transport properties of bulk (Ga,Mn)As layers and of their anisotropies
• spintronic devices fabricated from such layers
• ramifications of spin-orbit interaction in electronic devices (spin Hall effect, spin injection Hall effect)
• special topics related to transport in short-period (100 nm and less) superlattices and in graphene
• quantum Hall effects
