Researchers from the FOM Foundation and the University of Groningen have developed a technique to produce graphene bridges in the shape of a hammock. Through these bridges the researchers transmit spin currents based on the magnetic moment of electrons. The new technique is important for spintronics equipment, which use the spin current for information storage and transfer. The researchers published their results on 18 June 2012 online in Nano Letters.
Although the theoretical predictions are positive about the spin current in graphene, the experimental results have yet to meet these expectations. The freely hanging graphene bridges were, however, found to be superb conductors for spin current.
