Abstract
The surface resistances of PrBa2Cu3O7 films provide evidence of patche s of superconductivity with transition temperatures of approximate to 92 K. The same samples have insulating de resistivities. We interpret this as evidence that PrBa2Cu3O7 is intrinsically superconducting, but contains Ba-site Pr ions that break pairs and destroy macroscopic sup erconductivity. The theoretical implications are discussed.
