Physica C-superconductivity and Its Applications - PHYSICA C, 2000
The existence of superconductivity in samples of PrBa2Cu3O7−δ (Pr-123) is still a polemic subject... more The existence of superconductivity in samples of PrBa2Cu3O7−δ (Pr-123) is still a polemic subject. To further study this problem, we have prepared high-quality polycrystalline Pr-123 samples by following a sol-gel method, associated with heat treatment in inert atmosphere. In this paper we report the structural, thermal and magnetic properties of superconducting sintered-polycrystalline Pr-123 and give a descriptive explanation about its unique dependence on the preparation procedure. The list of evidences of superconductivity in Pr-123 is further expanded with new data on a superconducting thin film. The present results confirming the occurrence of superconductivity in Pr-123 revitalizes the hypothesis that superconductivity originates outside the cuprate-plane.
