| Popis: | The critical current density and the resistive transition curves of Ag-sheathed, textured (Bi/sub 1-x/Pb/sub x/)/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub 10/ tapes have been studied in magnetic fields up to 12 T. The results can be described by the modified flux creep model proposed by E. Zeldov et al. (1990). It is shown that this model yields a simple explanation for the exponential field dependence of the critical current density in high-temperature superconductors. > |
