Abstract

For the high TC system of TlBaCaCuO1, it is specially interesting to investigate the formation of films from sputtered BaCaCuO2. In such experiments, a Tl-free target of BaCaCuO is used for the film deposition and therefore the contamination problem of the vacuum system can be avoided. Using such rf sputtered BaCaCuO films, it is necessary to carry out oxidation and Ti diffusion to form the final compound. In this paper, some of the experimental results on the deposition of BaCaCuO thin films are first described. Variation of composition in the BaCaCuO films with the heat treatment is then presented.
