High Field Quantum Spin Hall State in Graphene
Using the high magnetic fields available at the NHMFL, users from MIT were able to observe a quantum spin hall (QSH) state in graphene. The QSH state results in two oppositely oriented spin currents flowing clockwise and counter clockwise around the edge of the graphene flake without dissipation effects. This discovery further advances the exciting work being done to bring about spin based electronics.
