Flux Pinning and J_c-B-T Surface in High-J_c BSCCO-Ag Tapes
Critical current densities Jc and pinning energies U for two high-Jc Ag-clad Bi2Sr2Can− 1CunOx tapes with N=2 and 3 respectively have been studied in the temperature range 7– 110K and magnetic field B<- 6.5T. In both types of tapes Jc and the pinning force density Fp=JcB show scaling with B for T/Tc≥ 0.3 analogous to that observed in high-Tc epitaxial films. The suitable scaling field B*(T) is the field of maximum Fp(Fpmax). In both tapes the magnitude and temperature dependence of B* is associated with pinning energy U(B, T).
