Abstract

The bulk superconductor Tl₂Ba₂Ca₃Cu₄O₁₂ with T_c (onset) above 112 K has been prepared and structure and chemical composition were examined by X-ray powder diffraction, analytical (EDX) and high resolution electron microscopy. Unit cell dimensions for the tetragonal cell determined by the least squares method are a = 3.853 (1) A ̊, c=41.98 (3) Å. The transition temperature, T_c, of the double layered Tl system increases with the number of Cu-O layers (n) up to n = 3, while it turns down at n = 4.
