Stacking and Twisting Graphene Unlocks a Rare Form of Magnetism

Not only is graphene — a one-atom-thick sheet of carbon arranged in a hexagonal lattice — the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity. Now, a team of researchers has discovered that a variety of exotic electronic states, including a rare form of magnetism, can arise in a three-layer graphene structure.
