Abstract

Effects of organic additives on YBCO coated conductor prepared by MOD-TFA method were investigated. YBCO thin films were deposited on (100)-oriented single crystalline LaAlO$_3$substrates by conventional MOD-TFA process. The microstructures of YBCO thin films show labyrinth-like patterns. The origin of this microstructure was delineated by compositional inhomogeneity during the pyrolysis process of MOD process and it was shown that organic additives changes the microstructure and texture development of grown YBCO films
