“…However, J c (B) is strongly influenced by the strength of the flux pinning. At high fields, either intragranular [1][2][3][4][5][6] or intergranular 7,8 flux pinning becomes the main J c -limiting mechanism. Because different mechanisms determine J c (0) and J c (B), this leads us to believe that J c (B) may be optimized independently of J c (0).…”

“…Mechanical damage can affect the weak links versus the strong links to a different extent, which can be revealed in the change of the field dependence of I c [15]. The critical current through strong links in zero field (I s c0 ) can be obtained by extrapolating I c against H at elevated fields to zero field (figure 1) [16]. The value of I s c0 /I c0 can then be used to monitor the change of the strong-link connectivity as the tape is increasingly damaged.…”
