Abstract

Recently, Sheng and Hermann¹ reported the achievement of zero resistance at >100 K in the system Tl-Ca-Ba-Cu-O (TCBCO). Two superconducting phases were immediately identified² as Tl₂CaBa ₂Cu₂O_8+δ (2122) and Tl₂Ca ₂Ba₂Cu₃O_10+δ (2223). Here we confirm that zero resistance is achievable above 100 K in 2122-TCBCO synthesized by a fast solid-state reaction, and report a small positive pressure dependence of the transition temperature, as in Bi₂CaSr₂Cu ₂O_8+δ³.
