Four-terminal magnetoresistance measurements: (a) Longitudinal resistivity ρ xx measurements as a function of magnetic field ρ xx (B) at various temperatures. Hall resistivity ρ xy as a function of B at T = 1.9 K is shown. (b) Longitudinal resistivity measurements as a function of total magnetic field ρ xx (B tot) at various temperatures. (c) Longitudinal resistivity measurements as a function of the perpendicular component of the applied magnetic fieldρ xx (B perp) at various temperatures.
