摘要

Hg0.92Re0.18Ba2Ca2Cu3O8+d polycrystalline samples, with different oxygen content, were investigated by ac resistance measurements under different applied magnetic field (up to < 32 x 10(3w) A/m) and critical current measurements. The intergrain and intragrain regions have shown an improvement in the pinning energy and critical current density, as considering the precursor preparation with 10% of O-2 and 90% of Ar (optimal doped). In addition, the samples presented S-I-S junctions type as considering Ambegaokar-Baratoff theory. (C) 2004 Elsevier B.V. All rights reserved.
