Abstract

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.
