Nanoscale physics: Big moment for nanotubes

As an electron whizzes around the nucleus of an atom, it develops a magnetic signal known as an orbital magnetic moment. The size of the moment depends on the outer diameter of the electron's orbit, which is fixed by the size of the atom. Electrons orbiting around the walls of a carbon nanotube should also have an orbital magnetic moment, but this had previously never been detected. In this week's issue, E. D. Minot et al. are at last able to show that the resulting magnetic signal is exactly what's predicted.
