Superconducting properties of RBa/sub 2/Cu/sub 3/O/sub 7-//sub x/ compounds (R = Y, La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, and Yb) have been studied by dc electrical resistivity and ac magnetic susceptibility techniques. Except for R = La, which is superconducting below 50 K, RBa/sub 2/Cu/sub 3/O/sub 7-//sub x/ compounds exhibit sharp resistive and inductive transitions in the 90-K range. The nearly constant value of T/sub c/ for magnetic R ions indicates a very weak interaction between R ions, as anticipated from the known crystal structure of these materials. The effects of annealing in oxygen and argon, and air quenching, on the superconducting properties are also discussed.
