Physicists discover new quantum trick for graphene: magnetism

Sometimes the best discoveries happen when scientists least expect it. While trying to replicate another team's finding, Stanford physicists recently stumbled upon a novel form of magnetism, predicted but never seen before, that is generated when two honeycomb-shaped lattices of carbon are carefully stacked and rotated to a special angle.
