Figure 2: Sample characteristics establish the anomalous Hall effect.
From: Observation of anomalous Hall effect in a non-magnetic two-dimensional electron system
(a) Magnetotransport Rxx and Ryx at two representative temperatures. (b) Anomalous Hall effect component at different temperatures. The Landau level integer filling factors ν becomes visible at T<8 K. (c) Temperature dependence of the charge carrier density extracted from the ordinary Hall effect in high field. (d) Four-point resistance Rxx as a function of temperature. (e) Temperature dependence of the saturated value of anomalous Hall effect resistance 
. (f) AHE scaling: 
∝
. α=0.94±0.08 is observed between 2 and 10 K, whereas α>1 at higher temperature. (g) AHE angle increases with the decreasing temperature.
