Abstract

Two superconducting phases, Tl2Ca2Ba2Cu3O10 (2223) and Tl2Ca1Ba2Cu2)8 (2122), both with onset Tc near 120 K and zero resistivity at 100 K, have been isolated from samples in the Tl-Ca-Ba-Cu-O system. The new 2223 superconductor has a 5.40×5.40×36.253 pseudotetragonal unit cell. The 2122 superconductor, which appears to be structurally related to Bi2CaSr2Cu2O8, has a 5.44×5.44×29.553 pseudotetragonal subcell. The 2223 phase is probably related to 2122 by the addition of extra calcium and copper layers.
