Four-terminal magnetoresistance measurements:(a) Longitudinal resistivity ρxx measurements as a function of magnetic field ρxx(B) at various temperatures. Hall resistivity ρxy as a function of B at T = 1.9 K is shown. (b) Longitudinal resistivity measurements as a function of total magnetic field ρxx(Btot) at various temperatures. (c) Longitudinal resistivity measurements as a function of the perpendicular component of the applied magnetic fieldρxx(Bperp) at various temperatures.
