Abstract

Effects of Ti substitutions on superconductivity of Tl0.8Pb0.2Sr2-xTixCa0.9Y 0.1Cu2O7 (x = 0-0.7) and TlSr2-xTixCaCu2O7 (x = 0-0.4) ceramics have been investigated. Tl0.8Pb0.2Sr2-xTixCa0.9Y 0.1Cu2O7 (x = 0) was observed to superconduct with Tconset of 90 K and Tczero of 21 K. Substitution of Ti with x = 0.1-0.5 observed an increase in Tczero to 56-62 K with Tconset around 90 K. TlSr2-xTixCaCu2O7 (x = 0-0.2) was not superconducting above 20 K but for x = 0.3 superconductivity was observed with Tconset of 66 K and Tczero of 34 K.
