Using the zero-field-muon-spin-relaxation ({mu}SR) technique clear evidence has been found for antiferromagnetic ordering of Cu moments within the CuO planes of (Y{sub 1{minus}{ital x}}Pr{sub {ital x}})Ba{sub 2}Cu{sub 3}O{sub 7}. The Neel temperatures are approximately 285, 220, 35, 30, and 20 K for {ital x}=1, 0.8, 0.6, 0.58, and 0.54, respectively. For {ital x}=0.50 we observe a fast-relaxing component of the muon polarization in addition to a long-time tail, reminiscent of spin-glass behavior. This region of the phase diagram (0.5{le}{ital x}{le}0.54) corresponds to the existence of both superconductivity and magnetism. The fully developed local magnetic field for {ital x}{gt}0.54 is found to be {similar to}16 mT, but decreases to {similar to}12 mT at {ital T}=17 K for the {ital x}=1 sample, presumably due to the onset of Pr-ion ordering. Magnetic ordering also occurs in PrBa{sub 2}Cu{sub 3}O{sub 6}; the Neel temperature is {similar to}325 K.
