Critical currents in YBa2Cu3O7−x high-temperature superconducting thin films irradiated by 4-MeV electrons

A decrease in the critical current density Jc of a YBa2Cu3O7−x thin film is observed after its irradiation by 4-MeV electrons. It is shown that the temperature dependence of Jc agrees with the idea of a granular structure of the film, with intergranular contacts of the superconductor–metal–insulator...

Zusammenfassung:A decrease in the critical current density Jc of a YBa2Cu3O7−x thin film is observed after its irradiation by 4-MeV electrons. It is shown that the temperature dependence of Jc agrees with the idea of a granular structure of the film, with intergranular contacts of the superconductor–metal–insulator–superconductor type.
