Suppression and restoration of superconductivity in PrBa2Cu3O7

摘要

I review the principal experimental findings about superconductivity,suppression thereof, and related properties of RE_{1-x}Pr_xBa_2Cu3O7 in adecision-tree manner, eliminating the models substantially incompatible withestablished experimental facts, eventually focussing on the pf\sigmahybridization models and listing on a verbal level the interpretations of theexisting experiments as they emerge from such models.
