Abstract
The oxidation state of lanthanides in Eu1-xPrxBa2Cu3O7-delta and the s uperconducting properties and structure of these solid solutions are s tudied. Substitution of praseodymium for europium leads to the formati on of orthorhombic solid solutions over the entire: composition range. The introduction of praseodymium into EuBa2Cu3O7-delta causes a sharp decrease in T-c, presumably because the oxidation state of Pr in the solid solutionis higher than 3+, as evidenced by Pr K-alpha 1 chemical -shift measurements.
