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 ab2, with a and b linear in T. The perpendicular component c10 cm is 105 greater than a or b. Evidence for nonmetallic temperature dependence is found for the c ab 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.
