The interaction between an iron adatom and graphene is relevant for the development of spintronics devices. The corresponding material shows ferromagnetic behavior with strong spin polarization, instead of the gapless-semiconductor nonmagnetic features characteristic of pure graphene. The mechanism responsible for such a behavior is investigated by first-principles calculations. Using the molecular field approximation, the Curie temperature of the iron–graphene material is estimated to be around 367 K.
