Observation of magnetic domains in graphene magnetized by controlling temperature, strain and magnetic field

Abstract Since the production of ferromagnetic graphene as an extremely important matter in spintronics has made a revolution in future technology, a great deal of efforts has recently been done to reach a simple and cost-effective method. Up to now, controlling the magnetic properties at extremely...
