Spin transport in carbon nanotubes in the Fabry-Perot regime — •Miriam del Valle and Milena Grifoni — Institute of Theoretical Physics, University of Regensburg

We investigate the spin-dependent transport through carbon nanotubes connected to two ferromagnetic leads in the ballistic regime. The effect and origin of the phases acquired by electrons upon scattering at the contact interfaces are analyzed. These phases greatly determine the Fabry-Perot patterns obtained in this transport regime. With stress on the nanotube fingerprints, the magneto-resistance is calculated with the inclusion of spin-orbit effects, which are not negligible due to the finite curvature of the nanotubes.
