Abstract

The resistivity anisotropy has been measured in seven single crystals of YBa2Cu3O7. We find that the anisotropy is between 56 and 110 at 290 K, increasing to 250 just above Tc (9093 K). While the out-of-plane resistivity c is close to the Mott limit, the large in-plane resistivity ab (120150 cm at 290 K) implies a large metallic parameter (kFl31) and long electronic mean free path (67 AI at 100 K). Both c and ab are well described by the equation =A/T+BT recently proposed by Anderson and Zou.
