Abstract

Using a tight-binding model within the mean-field approximation, the effects of different spin configurations on transport through carbon nanotubes are studied. It is observed that, in the absence of external magnetic field, the mean-field ground states of both semiconducting and metallic nanotubes are antiferromagnetic. As regards electronic/transport properties, a gap opens in the density of states of the metallic tubes for weak applied magnetic fields, and the magnetic field separates the conductance characteristics of spin-up and spin-down carriers.
