Description	Journal: Superconductor Science and Technology Microstructure and microchemistry characterizations have been made using analytical transmission electron microscopy in order to correlate extended defect formation to intergranular and intragranular current density values. AC magnetization curves as a function of applied magnetic field at 4.2 and 77 K have been obtained. The results show that a large density of twins favours a high intragranular critical current density. In addition, the formation of cationic non-stoichiometric phases can act as vortex pinning centres. The relatively high intergranular current density is in good agreement with the observed absence of intergranular grain boundary phases.
