Description
The single phase of Y1-xPrxBaSrCu3O7-δ has been investigated by powder X-ray diffraction and temperature dependence of the resistivity. It is found that the system undergoes an orthorhombic-to-tetragonal transition at x=0.5. Superconductivity still survives until x=0.7. These results have been compared with those of the Y1-xPrxBa2Cu3O7-δ system, which was discussed in terms of the Pr-O covalent bonding effect. ((orig.))
