Abstract
Through magnetic linear dichroism spectroscopy, the magnetic susceptibility anisotropy of metallic single-walled carbon nanotubes has been extracted and found to be 2-4 times greater than values for semiconducting single-walled carbon nanotubes. This large anisotropy is consistent with our calculations and can be understood in terms of large orbital paramagnetism of electrons in metallic nanotubes arising from the Aharonov-Bohm-phase-induced gap opening in a parallel ¯eld. We also compare our values with previous work for semiconducting nanotubes, which con¯rm a break from the prediction that the magnetic susceptibility anisotropy increases linearly with the diameter.Citation
