Graphene bilayer provides efficient transport and control of spins
(PHYSorg.com Nanotechnology)

University of Groningen physicists in collaboration with a theoretical physics group from Universität Regensburg have built an optimized bilayer graphene device that displays both long spin lifetimes and electrically controllable spin-lifetime anisotropy. It has the potential for practical applications such as spin-based logic devices. The results were published in Physical Review Letters on 20 September.
