Abstract

⁶³Cu spin-lattice relaxation rate has been measured in annealed and as-grown samples of Tl₂Ba₂Ca₂CU₃O₁₀. We found for the first time that T_c 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 T_c of 8K in terms of the change in potential scattering due to crystal imperfection which is likely caused by Tl-substitution of Ca site.
