| Typical spin transfer pattern in N = 19-ZGNR and N = 20-AZGNR, with exchange splitting 200 v F ħ / e meV. (a) ZGNR spin current at ε for N = 19; (b) ZGNR spin transfer torque at ε for N = 19; (c) ZGNR spin current at − ε for N = 19; (d) ZGNR spin transfer torque at − ε for N = 19; (e) ZGNR spin current at ε for N = 20; (f) ZGNR spin transfer torque at ε for N = 20. Each panel illustrates spin current or transfer torque in three spin directions induced by a charge current in the x direction. Results of electron-like incident state at ε = 50 v F ħ / e meV and hole-like state at − ε for ZGNR are shown in (a,b) and (c,d), respectively. For AZGNR, we only show electron-like states since there is no qualitative difference from hole-like states. |
