Magnetic characterization has been performed on the members of the cuprate-niobate RBa{sub 2}Cu{sub 2}NbO{sub 8} (R = Pr, Nd, and La) series and R{sub 1.5}Ce{sub 0.5}Sr{sub 2}Cu{sub 2}NbO{sub 10} (R = Pr, Eu, Nd, and Sm) series. The PrBCNO samples show a signature in the magnetization of a magnetic ordering at 12K. The PrCSCNO sample is nonsuperconducting and shows two distinct orderings at 17K and 53K. No such magnetic phase transition is observed down to 2K in the Nd and La based RBCNO materials or the Nd, Sm, and Eu based RCSCNO materials. Measurements of the lower critical field curve, dc irreversibility line, and critical current densities are reported for each of the superconducting NdCSCNO, SmCSCNO, and EuCSCNO compounds.
