| Summary: | A simple method for growth of Tl-based superconducting thin Annealing and diffusion of thallium were carried out conducted at 820 C in 98% Ar + 2% 02 by volume flowing gas diffraction, electron microprobe analysis, microwave films can be prepared by this simple method. The problem of films is described. In this method, the precursor was in one atmosphere of oxygen for formation of the Tl-2212 measurement and measurement of resistance versus temperature. metals or a Ba-Ca alloy and Cu metal. The precursor was then mixture. Representative samples were characterized by X-ray morphology of the thin films is discussed. oxidized at room temperature and in the atmosphere. phase. For the Tl-2223 phase, thermal processing was prepared in a vacuum chamber by deposition of Ba, Ca and Cu simultaneously at a temperature ranging from 920 C to 940 C The results show that highly oriented superconducting thin |
