摘要：

Anisotropic electrical resistivity and magnetic susceptibility are measured on single crystals of Sr(14-x)A(x)Cu(24)O(41) (A = Ca, Y). This material contains two-leg antiferromagnetic spin ladders that are progressively doped with hole carriers upon Ca substitution and thus determine the charge-transport properties. Application of hydrostatic pressure to this system has an effect similar to Ca substitution, increasing the hole density in the ladders. The resistivity shows remarkable anisotropy, indicative of a one-dimensional electronic state.
