Abstract
The co- existence of superconductive and magnetic properties of Yi - xPrxB(i2Cu307-s
has been investigated. The suppression of Tc by the Pr concentration can be described
by the Abrikosov-Gorkov pair-breaking like relation , and hybridization between Pr
4f states and conduction bands may play an important role in the suppression of Tc .
We have determined the dependency of Tc on the impurity concentration. Superconductivity
vanishes at a certain critical concentration. We have made a detailed study
of co- existence of superconductivity and ferromagnetism in the concentration range
close to the critical . We also study the effect of spin-spin interaction at T < Tm
and spin-electron interactions on superconducting transition point. Superconductivity
appears together with ferromagnetism but persists only until the ferromagnetic
effect is not sufficiently large
