Description

The current-voltage characteristics of several high-temperature superconducting YBa2Cu3O7 thick films and bulk samples have measured. The experimental results were compared to the prediction of dissipation in superconductors made by the Ambegaokar-Halperin (A-H) model. Found that the A-H model consistently fit all the data well over the entire range of measured values. The critical current and electrical resistivity of the junction was calculated using the fitting results and related to the gamma exposure dose. The observed changes in the grain boundary properties with the dose were analyzed in the text
