Following a recent report concerning a "nonmagnetic-magnetic transition" of Pr ions in superconducting (RE1-xPrx) Ba2Cu3O7-δ (RE=Y and rare earth) systems in accounting for the deviation from Abrikosov-Gor'kov magnetic pair-breaking theory observed in the systems with relatively small RE3+ radii, this paper reports a study on another system with RE=Yb, which has even smaller ionic radius. The superconducting transition temperature of this system remains practically constant at 92 K for x up to about 0.1 before decreasing with increasing x as to be expected from the Abrikosov-Gor'kov theory.
