Current-voltage curves of a cylinder with a power-law E(J)

The current-voltage V(I) curve of a cylinder of radius a with E=E c(J/Jc)\J/Jc\n-1 is numerically calculated for a set of given values of a, Ec, Jc, and the I-sweeping rate R at n=5, 10, 20, and 40. After deriving a scaling law and defining a full penetration point for each calculated I-sweeping-up curve, the results are extended to those for any values of parameters and so can be conveniently used in the study of high-temperature superconductors. © 2006 American Institute of Physics.
