The influence of substitution of Ba2+ with Sr2+ on superconducting and magnetic properties of ceramic RBa2-xSrxCu3O7-δ (R Gd, Dy; x = 0.5, 1.0) samples with different oxygen content has been investigated. In contrast to YBCO, RBa2-xSrxCu3O7-δ becomes superconducting in a narrow range of δ between 0 and 0.35. Magnetic phase diagrams were constructed for these compounds.
