Abstract

The temperature and magnetic field dependence of J _c(T,H) in YBa ₂Cu ₃O _7-δ (YBCO) thick films were studied as a function of film thickness. A detailed measurement of J _c(T,H) was found to be necessary for assessing the bulk pinning strength of YBCO films. A high-field J _c crossover of the YBCO films was observed in the elevated temperatures as the thickness changed from 0.2 to 3 νm. The results were found to be of immense importance for the coated conductors used in the applications operated in high fields and at elevated temperatures.
