Abstract

63Cu spin-lattice relaxation rate has been measured in annealed and as-grown samples of Tl2Ba2Ca2CU3O10. We found for the first time that Tc increases as a result of decrease of the residual density of states at the Fermi level due to the improvement of crystal order by annealing. A 2-dimensional d-wave superconductivity model accounts for the increase of Tc of 8K in terms of the change in potential scattering due to crystal imperfection which is likely caused by Tl-substitution of Ca site.
