Abstract
Recent reports about observations of superconductivity in PrBa2Cu3O7 raise a number of questions. (i) Of the various theories striving to explain the Tc suppression in PrxY1−xBa2Cu3O7, are there any compatible with possible superconductivity in stoichiometric PrBa2Cu3O7? (ii) If this superconductivity is not an experimental artifact, are the superconducting carriers (holes) of the same character as in the other high-Tc cuprates, or do they represent another electronic subsystem? (iii) Is the underlying mechanism the same as in other high-Tc superconductors? I present an answer to the first two questions, leaving the last one open.
