Abstract
The resistivity ρ and Hall coefficient have been measured for samples of the two-plane superconductor (∼124 K) with different annealing histories. The observed temperature dependence ∼1/T (up to 470 K) matches the steep dependence previously seen in 90-K and indicates low-impurity scattering. We find T-linear behavior for ρ in the lowest-resistivity samples and confirm that cot∼. These findings add support to Anderson’s proposal of distinct longitudinal and transverse scattering times.
