摘要：

Two PMP-processed YBCO specimens fabricated at different melting temperatures were investigated. The critical current density (J(c)) was determined from flux-profile measurements. One sample was re-annealed at 880 degrees C for 30 hours to reduce the number of stacking faults and dislocations. The J(c) values and irreversibility lines of this sample were measured before and after re-annealing. The results indicate that stacking faults and dislocations strongly influence the flux-pinning behaviour of PMP-processed YBCO superconductors.
