Description
Zero-field muon-spin-rotation ({mu}SR) measurements on (Y{sub 1-x}Pr{sub x})Ba{sub 2}Cu{sub 3}O{sub 7} (x = 1.0, 0.8, 0.6, and 0.54) show evidence for antiferromagnetic ordering of the Cu moments within the Cu--O planes, with Neel temperatures 285,220, 35, 30, and 20 K respectively. For x = 1.0 the local muon magnetic field is {approximately}16 mT, but decreases to {approximately}12 mT at 17 K, due to additional magnetic ordering. The zero-field data, in conjunction with transport data, allow construction of a complete diagram for this system. Transverse-field (1 kOe) {mu}SR data for x = 0.2 ({Tc} = 75 K) show that the muon depolarization is determined primarily by the Cu nuclear moments for T>{Tc}. Fitting the superconducting-state data to a BCS model yields an extrapolated zero-temperature magnetic penetration depth of 2170{angstrom}. 9 refs., 3 figs.
