Superlattice Structure of TlBa2Ca2Cu3Oy and Tl2Ba2Ca2Cu3Oy (c/2)

Abstract
A new phase, Tl1.5Ba2Ca2Cu3O y , with a superlattice structure of 1223 and 2223 (c/2) has been synthesized. The presence of this phase was confirmed by powder X-ray diffraction (XRD) and transmission electron microscope (TEM).
