Abstract

Synthesis and processing parameters for (Hg_1-xBi_x)Ba₂Ca₂Cu _3.1O_y were optimized for growth at temperatures suitable for growth on Ag and Au substrates (<850°C). Use of Bi₂CuO₄ as a Bi source combined with variations of BaCaCuO precursor phase assemblages allowed the formation of some liquid phase during the reaction and resulted in dense (Hg_1-xBi_x)Ba₂Ca₂Cu _3.1O_y samples with aligned colonies of grains. Magnetization measurements in fields up to 30 T indicated good intergrain coupling within the large grain colonies. The results of the Bi doped samples are compared with those of previously reported Re doped samples.
