Abstract
V-I characteristics of Ag-clad BPSCCO tape have been studied in the te mperature (T) range 80-106K and magnetic fields (B) up to 60 mT. The z ero-field J(c) at 77K is 10100 A/cm2. J(c) showed power law variations with T and B, characteristic for the intragranular flux creep. The ma gnitude and variations of the slope resistance R(f) with T and B are c onsistent with the flux flow in low fields. Very broad and featureless critical current distribution function (CCD) is ascribed to the varia tion in the flux pinning energies within BPSCCO.
