Evidence for One-Dimensional Charge Transport in La(2-x-y)Nd(y)Sr(x)CuO(4).

Doping dependences of the resistivity and the Hall coefficient are presented for neodymium-doped lanthanum strontium cuprate (La(1.4-x)Nd(0.6)Sr(x)CuO(4)) in the static spin-charge stripe ordered phase. For doping concentration x </= 1/8, a rapid decrease in the magnitude of the Hall coefficient at low temperatures provides evidence for one-dimensional charge transport, whereas for x > 1/8, the Hall coefficient remains relatively large in the ordered phase. The results indicate a crossover from one- to two-dimensional charge transport taking place at x = 1/8.
