ABSTRACT:
This invention is directed to a method of forming an article comprised of a substrate and an electrically conductive crystalline rare earth alkaline earth copper oxide thin film containing an R.sub.1 A.sub.2 C.sub.3 crystalline phase over an R.sub.2 A.sub.1 C.sub.1 crystalline phase, where R.sub.1 A.sub.1 and C represent rare earth, alkaline earth, and copper, respectively.
