摘要：

We have investigated a temperature dependence of the critical current density J(c)(T) and a dependence of the energy barrier for vortex motion on current density U-eff(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 J(c)(T) and U-eff(J) The results revealed that both quantities exhibit a universal behaviour governed by an intrinsic property of these superconductors; Josephson nanostructures in the a-b planes of YBCO and TBCCO.
