(a) SEM image of a setup allowing to detect the orientation of the magnetization direction of a CoFe nanodisk by two orthogonal CoFe wires. Al is used for the nonmagnetic parts. The current is injected through the nanodisk, while two non-local detectors are measuring the non-local spin signal V 1 and V 2. The in-plane orientation of the field is parametrized by the angle α. (b) Spin signals vs. field orientations α at 300 K. The applied field is kept constant in amplitude (B = 180 mT). As the magnetization of the nanodisk follows the field, the spin accumulation orientation varies. The voltage measurements using the two perpendicular CoFe wires allows measuring the projection of this spin accumulation on the X, Y basis.
