11. The B field that forces the magnetizations into the field direction is larger for lower temperatures.

14. The HR and LR state was realized, respectively, by applying a sufficiently high magnetic field to align the magnetization into a direction where, at Vg =0, a high and low resistance was observed. Here, along 120°and 90°, respectively.

16. Only a limited Vsd range is accessible for fitting: for smaller voltages the conductance gets immeasurable low while for higher voltages the temperature dependence vanishes.
