The longitudinal and Hall resistances as a function of B at various T. (a) The longitudinal (R_xx) and (b) Hall resistances (R_xy) as a function of B at various T. From top to bottom: T = 4.2, 20, 40, 60, and 80 K, respectively. The inset to (b) shows the carrier concentration n as a function of T determined by the Hall slope. (c)R_xx(B)/R_xx(0)−1 against B.
