Graphene makes its mark on spin Nov 15
When researchers first found a way of making two dimensional sheets of carbon atoms two years ago, they could not have imagined how versatile it would be. So far "graphene" has been envisaged in applications from transistors to hydrogen storage. Now, physicists from the US claim that the structure can conduct electrons of one spin orientation but not the other. This property could enable graphene to be used to generate, manipulate and detect electron spins in "spintronic" circuits (Nature 444 347).
