Abstract
We report measurements of the current-voltage (I-V) characteristics of a sample of Pb0.2Hg0.8Ba2Ca1.75Cu3Ox at 77 K, 27 K and 4.2 K in appli ed magnetic fields varying from 0 to 6 T. These data are fitted very w ell by a modified Ambegaokar-Halperin model. Useful information about the material, including its critical current and pinning potential, ma y be obtained from the fits.
