摘要：

The surface resistances of PrBa2Cu3O7 films provide evidence of patches 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 superconductivity. The theoretical implications are discussed.
