ABSTRACT The aim of the project is to prepare the high temperature superconducting thin films which can satisfy the need of future applications in the field of power transmission. By using biaxially textured Ni (001) and Ag (110) as substrates, the YBCO films with high critical current were obtained under the optimized deposition conditions. Some results were obtained as follows: We developed a simple approach to prepare YBCO films doped with Ag nanograins.
