摘要：

We report on spin-dependent transport measurements in carbon nanotubes based multiterminal circuits. We observe a gate-controlled spin signal in nonlocal voltages and an anomalous conductance spin signal, which reveal that both the spin and the orbital phase can be conserved along carbon nanotubes with multiple ferromagnetic contacts. This paves the way for spintronics devices exploiting both these quantum-mechanical degrees of freedom on the same footing.
