Abstract
Anisotropic electrical resistivity and magnetic susceptibility are mea sured 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 prog ressively doped with hole carriers upon Ca substitution and thus deter mine the charge-transport properties. Application of hydrostatic press ure to this system has an effect similar to Ca substitution, increasin g the hole density in the ladders. The resistivity shows remarkable an isotropy, indicative of a one-dimensional electronic state.
