De Martino, A. & Egger, R. (2005). Rashba spin-orbit coupling and spin precession in carbon nanotubes. Journal of Physics: Condensed Matter, 17(36), pp. 5523-5532. doi: 10.1088/0953-8984/17/36/008
Abstract
The Rashba spin-orbit coupling in carbon nanotubes and its effect on spin-dependent transport properties are analyzed theoretically. We focus on clean non-interacting nanotubes with tunable number of subbands $N$. The peculiar band structure is shown to allow in principle for Datta-Das oscillatory behavior in the tunneling magnetoresistance as a function of gate voltage, despite the presence of multiple bands. We discuss the conditions for observing Datta-Das oscillations in carbon nanotubes.
