Structural, thermal and magnetic properties of Pr-123 polycrystalline and thin film superconductors

We report the structural, thermal and magnetic properties of superconducting PrBa 2Cu 3O 7− δ (Pr-123). The existence of superconductivity in samples of Pr-123 is still a polemic subject. To further study this problem, we have measured thin films and high-quality polycrystalline bulk samples by foll...

Zusammenfassung:We report the structural, thermal and magnetic properties of superconducting PrBa 2Cu 3O 7− δ (Pr-123). The existence of superconductivity in samples of Pr-123 is still a polemic subject. To further study this problem, we have measured thin films and high-quality polycrystalline bulk samples by following a sol–gel method, associated with heat treatment in argon atmosphere. The present results confirm the occurrence of superconductivity in Pr-123 polycrystalline and thin film samples.
