Abstract
The penetration depth lambda and the surface resistance R(s) of BSCCO single crystals were measured at 10 GHz using a special Nb cavity. At low temperatures, Delta lambda proportional to T-2, inconsistent with pure s- or d- wave symmetry, but suggestive of strong impurity scatter ing. Near T-c the data are inconsistent with a two-fluid or BCS s-wave model. An unusual peak is observed in R(s) near T-c and is attributed to fluctuations.
