The results of superconducting and magnetic studies on the Y{sub 1{minus}x}Pr{sub x}Ba{sub 1.5}Sr{sub 0.5}Cu{sub 3}O{sub 7{minus}{delta}} system with 0{le}x{le}1.0 are reported. Superconducting transition temperature (T{sub c}) decreases with increasing x. The behavior of T{sub c}(x)/T{sub c}(0) versus Pr concentration x in this system is similar to that observed in the Y{sub 1{minus}x}Pr{sub x}Ba{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} system but the critical Pr concentration (x{sub cr}) required for complete suppression of superconductivity appears to be higher in the present system. Surprisingly, the N{acute e}el temperature T{sub N} of PrBa{sub 1.5}Sr{sub 0.5}Cu{sub 3}O{sub 7{minus}{delta}} is found to be higher ({approximately}21 K) than that for PrBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} ({approximately}17 K) with nearly the same oxygen content. This may imply stronger interaction of Pr-4f moments with the carriers in the Cu{endash}O{sub 2} planar network in the present system and yet the T{sub c} suppression is relatively weaker. {copyright} {ital 1997 American Institute of Physics.}
