Abstract
Superconducting properties of Pr123 and microscopic structural differences
between the superconducting and non-superconducting Pr123 crystals are revi
ewed. It is shown that the variety of physical properties of Pr123 is close
ly related to Cu deficiency at the chain site and our experimental results
are consistently explained with a model that the Pr 4f-O 2p hybridization f
orms a narrow band and carriers are localized by a kind of atomic disorder
in non-superconducting crystals.
