Abstract

We report the first measurement of the magnetic penetration depth (T,) in single crystals of YBa2Cu3O7- (0.1). Results are consistent with conventional s-wave pairing, and yield penetration depths of ab(0)=141530 and c(0)>7000, parallel and perpendicular to the basal plane, respectively. Comparative data on sintered YBa2Cu3O7 are also shown to be consistent with the single-crystal results. The muon-spin-rotation data, together with specific-heat results, indicate a two-dimensional carrier density of 2D8×1014 carriers cm-2 and a basal-plane effective mass of mab*me10.
