Abstract
In order to investigate a relationship between the carrier concentration and negative magnetoresistance in the underdoped region, we have performed out-of-plane electrical resistivity measurements for underdoped Bi 2 Sr 1.6 La 0.4 CuO 6+δ single crystals. Giant negative magnetoresistance has been observed in the most abundant carrier sample with δ = 0.12 in our experiment. The negative magnetoresistance reduces with decreasing carrier concentration.
