Induced magnetic moment in graphene. a Theoretical prediction of magnetic moments in graphene due to hydrogen. b Magnetic moments due to hydrogen doping detected by spin transport measurements at 15 K. The device was measured after 8 s hydrogen doping. c Schematic of graphene exchange coupled to an atomically flat yttrium iron garnet (YIG) ferromagnetic thin film. d Anomalous Hall resistance measurements on magnetic graphene at different temperatures. a, b
