Abstract

Melt textured single domain ReBa2Cu3O7 (Re = Y,Nd) samples were post-processed, either under high oxygen pressure (PO2 ≤180 bar) or under cold isostatic pressing (CIP) conditions. We show that CIP processing can lead to critical current enhancements up to 100% at 77K. The analysis of the evolution of the microstructure by TEM allows us to attribute the enhanced pinning to 1/6[031] partial dislocations which are distributed anisotropically within the (001) plane. In Nd123/422 composites we demonstrate that high oxygen pressure annealing enhances interface pinning in parallel with a reduction of the fishtail anomaly due to the presence of Nd-Ba antisite defects.
