摘要：

The I-V characteristics of silver-sheathed PBSCCO tapes have been measured at 4.2 K and 77 K in magnetic inductions up to 1.7 T applied parallel to the c-axis of the tape. The silver has dramatic effects on the transport current which leads to a misrepresentation of the V-I characteristics of the superconductor. On correcting the data, linear log (V)-log(I) plots are obtained which are typical of a logarithmic pinning potential. The effect of the silver on the estimate of I(c) has also been investigated and we have found that provided a small voltage criteria (< 1 muV) is used its effect can be neglected.
