| Abstract: | The recent experimental observation of the substitution of
praseodymium (Pr) in high transition temperature (Tc) superconducting Y123 compounds gives rise to very
interesting properties, such as monotonic decrease of Tc with increase in Pr concentration which is not
satisfactorily explained yet. The depression of Tc is due to hole filling/hole localization, magnetic
pair breaking or some kind of disorder/dislocation is still not clear. The
depression of Tc in Y1-xPrx
Ba2Cu3O7-x has been explained using
magnetic pair breaking, hole filling and disorder. It has been argued that the
disorder along with hole filling is responsible for suppression of Tc and subsequently to lower
order parameter (∆). |
