Spin transport in a Zigzag normal/ferromagnetic graphene junction |
Profile of energy-associated spin transfer torque and frequency for electron-like incident current. The energy is measured in 100 v F ħ / e meV within the same exchange splitting. (a) Energy-associated spin transfer torque at the interface for N = 19-ZGNR; (b) Frequencies of spin precession versus Fermi energy for N = 20-AZGNR. |
