Sažetak
AC susceptibility and V-I characteristics of a well characterised Ag-clad Bi-Pb-Sr-Ca-Cu-O tape have been studied in the temperature (T) range 77-106 K and magnetic fields (B) up to 0.06 T. The intrinsic critical current density Js (from ac susceptibility) is 30000 A/cm2 at 77 K whereas the transport critical current density Jc (from V-I curves) is 10100 A/cm2 at the same temperature. Both Js and Jc showed power law variations with T and B, respectively, characteristic for intragranular flux creep. From the dissipation within the core the differential resistance Rf (associated with the flux flow) has been deduced. The magnitude and the variations of Rf with T and B are consistent with those due to flux flow in type II superconductors in low field. From d2 V/d I2 vs I curves very broad critical current distribution CCD has been deduced. The most probable Jc within the core is Jcp ≃ 2.4Jc and the maximum one Jcm ≃ 5Jc. Such large Jcm enables further improvement of Jc in Ag-BPSCCO tapes.
