Abstract A Superconductor thin film applications such as microelectornics require a high quality films. the judgment that the film has high quality is that the film is epiaxial grown, has high transition temperature, Tc, and a strong uppercritical fied , Bc2, as wall as large critical current density , Jc, .to achieve haigh critical properties the flux lines should be pinned by the interaction with the defects in the film. |
