Graphene may be set to revolutionize electronics, but its small spin–orbit coupling limits its potential in spintronics. It is now shown, however, that adding hydrogen atoms can greatly enhance the magnetic properties of graphene. This then enabled the observation of the spin Hall effect, essential for controlling spin currents.
