Magneto-electric coupling in zigzag graphene nanoribbons
J. Jung, A. H. Macdonald
Zigzag graphene nanoribbons can have magnetic ground states with ferromagnetic, antiferromagnetic, or canted configurations, depending on carrier density. We show that an electric…

Theory of the Magnetic-Field-Induced Insulator in Neutral Graphene
J. Jung, A. H. MacDonald
Recent experiments have demonstrated that neutral graphene sheets have an insulating ground state in the presence of an external magnetic field. We report on a -band tight-bindi…

Carrier Density and Magnetism in Graphene Zigzag Nanoribbons
J. Jung, A. H. MacDonald
The influence of carrier density on magnetism in a zigzag graphene nanoribbon is studied in a -orbital Hubbard-model mean-field approximation. Departures from half-filling alter…
