The longitudinal and Hall resistances as a function of B at various T. (a) The longitudinal (Rxx) and (b) Hall resistances (Rxy) 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)Rxx(B)/Rxx(0)−1 against B.
