Abstract

The transport behavior of the high Tc superconducting thin films is of importance both for practical reasons in applications and for fundamental reasons in relation to microstructures and measurement conditions. The critical current density is one of the most important superconducting parameters in determining the possible application of the new oxide superconductors. It is also important for understanding the physical properties of these materials in connecting with the various theories.1–5
