Abstract
A strongly anisotropic resistivity tensor was measured from Tc=81 to 600 K in crystals of the new high-Tc superconductor Bi2Sr2.2Ca0.8 Cu2O8. The a−b plane anisotropy is ρaρb≈2, with ρa and ρb linear in T. The perpendicular component ρc∼10 Ω cm is 105 greater than ρa or ρb. Evidence for nonmetallic temperature dependence is found for the ρcρab resistivity ratio. The data are consistent with the notion of quasiparticle tunneling between planes, but an alternative explanation in terms of weak interplanar coupling by topological defects is also presented.
