a–c, The forward bias direction (VSD = 1 mV) for different magnetic fields, showing the same features as the experimental data presented in Fig. 2. d–f, The blocked bias direction (VSD = − 1 mV) for the same magnetic fields. For zero magnetic field, the blockade is lifted at the corners of the bias triangle, where back and forth tunneling to source (or drain) allows lifting the blockade. The effect is even larger at finite parallel magnetic fields, where the spins are tilted into the plane of the BLG.
