Abstract	Magnetotransport properties are systematically investigated on single crystals with different carrier concentrations changed by oxygen content. The in-plane resistivity decreases rapidly with increasing carrier concentration. Large negative magnetoresistance was observed in all the single crystals. A magnetic-field–driven sign change of the slope in resistivity at and a magnetic-dependent energy gap in the range 20– are observed in highly doped crystals, while they are absent in the crystals with low carrier concentrations. In addition, a thermally activated resistivity induced by magnetic fields was observed at low temperatures below in highly doped crystals. It is concluded that the magnetotransport properties are quite sensitive to the carrier concentration.
