- B - T surface of high- tape
Abstract:Critical current density of an Ag-clad tape has been studied in the temperature range 7 - 77 K and magnetic field For , and the pinning force density show scaling behaviour with the scaling field corresponding to the field of maximum . At intermediate fields , whereas well below and above , shows the asymptotic variations with and 3 respectively. The thermally activated flux motion and the thermal smearing of the pinning potential describe equally well the temperature dependence of for K. These findings show that in finite fields well-prepared tape behaves as homogeneous high- superconductor (HTS). The implications of these results for the understanding of in HTSs and the applications of tapes are briefly discussed.
