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 2Cu2O8+δ (2122) and Tl2Ca 2Ba2Cu3O10+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 2O8+δ3.
