Paper Abstract

We have investigated a temperature dependence of the critical current density Jc(T) and a dependence of the energy barrier for vortex motion on current density Ueff(J) in several YBCO and TBCCO thin films. The measurements have been done using rings in a persistent mode and a scanning Hall probe to record Jc(T) and Ueff(J). The results revealed that both quantities exhibit a universal behavior governed by an intrinsic property of these superconductors; Josephson nanostructures in the a-b planes of YBCO and TBCCO.
