VG dependence of Ryx (a) and Rxx (b) for y=0.88 FET at T=0.5 K under various magnetic fields. The inset in b shows the magnetic field dependence of Rxx at VG=1.1 V (blue) and VG=−1.3 V (red). Blue and red arrows in the main panel of b represent gate voltages of VG=1.1 and −1.3 V, respectively. VG dependence of σxy (c) and σxx (d) at T=0.5 K under various magnetic fields. The inset in d plots the (σxy(VG), σxx(VG)) at various VG under magnetic field B=14 T.
