Abstract

of the samples, sigma(1)(T), gradually increases with the decrease of temperature, showing no peak below or at T-c, in notable contrast with the behavior found in the cuprates. The temperature-dependent quasiparticle scattering rate was analyzed in a two-fluid model, assuming the validity of the Drude description of conductivity and generalized expression for the scattering rate. This analysis allows us to estimate the range of the values of a residual surface resistance from 3 to 6 m Omega. DOI: 10.1103/PhysRevB.87.014506
