Abstract

There exists several techniques to synthesize TlBaCaCuO from precursor films. Recently, a two zone furnace technique was developed by DeLuca. Based on our experience on the two zone furnace technique, we systematically conducted a series of experiments in a tube furnace with a temperature gradient distribution. The BaCaCuO precursor films were fabricated by an ink method, and the Tl diffusion source was Tl₂O₃. Superconductive films were characterized by SQUID magnetization measurement, X-ray diffraction, SEM, and EDS. Experimental results will be summarized.
