我们用电阻探测核磁共振(RDMRI)研究了非平衡量子霍尔区的电子自旋极化。通过测量奈特位移，我们得到了量子线中电子自旋极化与源漏偏压的关系。电子自旋极化在动态核极化阈值电压附近出现最小值。
We performed the resistively-detected nuclear magnetic resonance (RDNMR) to study the electron spin polarization in the non-equilibrium quantum Hall regime. By measuring the Knight shift, we derive source-drain bias voltage dependence of the electron spin polarization in quantum wires. The electron spin polarization shows minimum value around the threshold voltage of the dynamic nuclear polarization.
