Abstract Zero and weak transverse fieldμ + SR measurements on PrBa2Cu3O x samples withx≈6 andx≈7 show ordered magnetism in both oxygen concentration limits. As expected for equivalent doping (nominally PrBa2Cu3O x ∼YBa2Cu3O x −0.5), neither sample is superconducting. Two muon signals are observed in thex≈6 sample, as in YBa2Cu3O6, but only one (the weaker) has the same local magnetic field as in YBa2Cu3O6. In thex≈7 sample, only one site is observed; its local field is reduced with respect to that of the primary site in YBa2Cu3O6 by a factor roughly consistent with the carrier-density dependence of the Cu ion moment in antiferromagnetic YBa2Cu3O x .
