Researchers from Japan demonstrated that forming honeycomb-like arrays of hydrogen-terminated nanopores on a graphene sheet can make it magnetic. The researchers think that the room-temperature ferromagnetism is caused by electron spins localized at the zigzag-shaped atomic-structured nanopore edges. This was predicted by theory and now has been shown in an experiment. This may one day lead us towards flexible, light, transparent and strong magnets and spintronics devices.
