Abstract

We have investigated the effects of heating rates in the calcination process on microstructures of Y123 precursor and final films. As a result, it was found that there is CuO segregation in the vicinity of the Y123 precursor film surface, when the precursor is prepared at a rapid heating rate in the calcination. In the case of heat-treating this precursor film in the crystallization process, many large pores and misoriented Y123 crystals tend to remain in the Y123 final film. It is important to control the heating rate in the calcination, in order to attain higher Jc of the Y123 final films.
