- W85530725 abstract "Graphene nanoflakes are interesting because electrons are naturally confined in these quasi zerodimensional structures, whereas confinement in bulk graphene would require a bandgap. Vacancies inside the graphene lattice lead to localized states and the spins of such localized states may be used for spintronics. We perform a tight-binding description of a nanoflake with two vacancies and include a perpendicular magnetic field via Peierls’ phase. The tunnel coupling strength and from it the exchange coupling between the localized states can be obtained from the energy splitting between numerically calculated bonding and antibonding energy levels. This allows us to estimate the exchange coupling J , which governs the dynamics of coupled spins. We predict the possibility of switching in-situ from J > 0 to J = 0 by tuning the magnetic field. In the former case, the ground state will be antiferromagnetic with Neel temperatures accessible by experiment." @default.
