    • Although a yield of 1 out 15 is low, it is comparable to the percentages obtained for two-terminal devices in Refs. (4 out of 30) and (1 out of 100).

    • This behavior was seen after a thermal cycling step and reproduced over eight consecutive curves. Similar effects can be deduced from Ref., Fig. 4.

    • For Fig. 3 we obtain αF =0.29. The structure in this figure is attributed to the magnetization rotation as function of the external magnetic field. Probably, repeated thermal cycling changed the magnetic domain structure of the electrode.

    • For model B, we assume the nanotube below the ferromagnetic electrodes to be diffusive and in between the electrodes ballistic (Ri,i+1 =0). We extract a spin polarization αF =0.21. We calculate a value of 170 Ω for the local spin-valve geometry, a factor 4 smaller to the measured value.

    • From the resistor model we find that the influence of contacts F1 and F4 in the nonlocal measurement is very small [∼1 Ω for Figs. 3 3 3; ∼3 Ω for Fig. 3].
