Researchers can magnetize graphene using hydrogen and could enable 1 milion fold improvement over todays hard drives
Graphene, an atomically thin sheet of carbon, has been intensively studied for the last decade to reveal exceptional mechanical, electrical, and optical properties. Recently, researchers have started to explore an even more surprising property—magnetism. Theories and experiments have suggested that either defects in graphene or chemical groups bound to graphene can cause it to exhibit …
