Abstract :
Magnetoplasmons in a graphene sheet immersed in a periodic magnetic field produced by a ferromagnetic nanowire membrane are analyzed. The periodic magnetic field modifies the classical cyclotron radii and generates a periodic non-uniform carrier density. Depending on the strength of the magnetic field and the corresponding cyclotron radii, different regimes requiring different treatments are identified and analyzed.
