Muon spin rotation and relaxation techniques have been used to study the superconductivity and magnetism in (Y{sub 1-x}Pr{sub x})Ba{sub 2}Cu{sub 3}O{sub 7} (0{le}x{le}1) and PrBa{sub 2}Cu{sub 3}O{sub 6}. Clear evidence for magnetic ordering of the Cu moments within the Cu-O planes is seen. Additionally, a lower magnetic transition is observed which, based upon previous work, has been associated with the ordering of Pr moments on the Y sublattice of the YBa{sub 2}Cu{sub 3}O{sub 7} structure. For x = 1, the upper Neel temperature T{sub N1} is {approximately}270 K and the magnitude of the fully developed local magnetic field is {approximately}16 mT. Below the lower Neel temperature T{sub N2} = 17 K, the magnitude of the static field is reduced to {approximately}12 mT. For 0.4{le}x{le}0.54, there appears to be a coexistence region of long-range magnetism and superconductivity. 4 refs., 5 figs.
