Abstract
We report the in-plane resistivity and Hall effect of crystals (0≤x≤1). We find that the anomalous temperature dependence of the normal-state Hall coefficient persists up to x=0.55, at which point the superconductivity is destroyed. The Hall cotangent (/) follows cot≊+γ(x), consistent with recently reported results for crystals. Our results suggest that Pr doping introduces localized magnetic moments into the planes. These moments act as scattering centers for charge carriers and contribute to the suppression of superconductivity.
