摘要

We report an efficient and highly reproducible method for the preparation of the almost monophasic Tl-1223 phase by partial substitution of Ba²⁺ into Sr²⁺ sites in the stoichiometric compositions of (Tl_0.6Pb_0.2Bi_0.2)(Sr_2-xBa_x)Ca₂ Cu₃O₉ (x=0.2-0.3). The as-synthesized samples have a superconducting transition temperature around 115 K which can be further increased up to 122 K after post-annealing at 820°C for 20 h in oxygen.
