我们通过实验证明，强关联二维电子系统的纵向电阻可直接定量测量其自旋极化。采用电检测电子自旋共振作为自旋态的独立校准，我们建立了磁输运与自旋极化之间无参数的关系，仅通过输运测量即可重构自旋极化。提取的自旋极化可定量解释电检测自旋共振信号的磁场和温度依赖性，还能在宽载流子密度和磁场范围内绘制电子液的磁态图。
英文摘要
We show experimentally that the longitudinal resistance of a strongly correlated two-dimensional electron system provides a quantitative measure of its spin polarization. Using electrically detected electron spin resonance to independently calibrate the spin state, we establish a parameter-free relation between magnetotransport and spin polarization, allowing the latter to be determined from transport alone. This approach enables the magnetic state of the electron liquid to be mapped across a broad range of carrier densities and magnetic fields.
