Extended Data Fig. 6: Temperature dependent measurements of the −3/5 state.
From: Observation of fractionally quantized anomalous Hall effect
Data are taken from device D(3.7°). a, Magnetic field dependence of Rxx (top) and Rxy (bottom) at selected temperatures and D/ε0 = 0. Rxy is measured in the configuration described in Extended data Fig. 4a, while Rxx is obtained from the configurations in Extended Data Figs. 4b and c. b, Arrhenius plot of Rxx. Solid line is the fit to equation \({R}_{0}{e}^{-\triangle /2{k}_{B}T}\). c, Arrhenius plot of δRxy = (5h/3e2-Rxy). Solid line is the fit to \({R}_{0}{e}^{-\triangle /{k}_{B}T}\). Extracted energy gaps from Rxx and Rxy measurements are similar, with values of 15(3) K and 14(2) K, respectively. The nonvanishing Rxx at base temperature can arise from large contact resistance, twist angle disorder, or interlayer electric polarization domains that connect probing contacts.
