Graphene has made a revolution in the material industry after the demonstration of the ability to successful isolation of graphene thin layers in 2004, due to its exclusive characteristics of electronic, optical, and mechanical properties. However, ideal graphene has no net magnetic moment due to a delocalized π-bonding in nature and has a zero bandgap which limits its practical applications in the world. Nevertheless, many studies have shown that by inducing magnetism into graphene, the mentioned limit can be overpowered which enables to apply especially in spintronics and memory storage devices. Therefore, this review paper discusses four possible techniques in improving magnetic properties on graphene monolayer, which are surface doping with adatoms, vacancy creation, substitutional doping, and edge modification, by providing the experimental, theoretical evidence and as well as their limitations, future research, and applications.
