摘要：
We report the structural, thermal and magnetic properties of superconducting PrBa2CU3O7-delta (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. (C) 2001 Elsevier Science B.V. All rights reserved.
