The antiferromagnetic (AFM) and superconducting (SC) phase-transition temperatures of Y{sub 1{minus}{ital x}}Pr{sub {ital x}}Ba{sub 2}Cu{sub 3{minus}{ital y}}{ital M}{sub {ital y}}O{sub {ital z}}, {ital M}=Fe,Co,Zn, were studied by magnetometry and {sup 57}Fe Moessbauer spectroscopy. For {ital z}{approximately}7, substitutions at all sites except those in the CuO{sub 2} planes (Pr,Fe,Co) cause superconductivity to disappear at {ital x}{sub {ital c}}=0.5 or {ital y}{sub {ital c}}=0.4 and antiferromagnetism to appear above {ital x}{sub {ital c}} and {ital y}{sub {ital c}}. For {ital z}{approximately}6, antiferromagnetism persists for all {ital x} and {ital y} values. On the other hand, substitution in the Cu(2) planes (Zn) suppresses both superconductivity at {ital y}{sub {ital c}}=0.24 for {ital z}{approximately}7 and antiferromagnetism for {ital z}{approximately}6. No antiferromagnetism is seen for {ital z}{approximately}7.
