  A method of regulating spin dynamics of the so-called magnetic graphene is
analyzed. Magnetic moments can be incorporated into graphene flakes and
graphene ribbons through defects, such as adatoms and vacancies. Local spins
can also be attached to graphene at hydrogenated zigzag edges. Spin flips can
be produced by transverse pulses and by connecting the sample to a resonance
electric coil. The action of the resonator feedback field strongly accelerates
spin reversal. The possibility of fast spin reversal is important for
spintronics and for quantum information processing allowing for an efficient
functioning of spin registers.
