Abstract

Bulk specimens of high T_c superconductors of TlBa₂Ca_{n - 1}Cu_nO_{2n + 3} (n = 2 - 5) have been synthesized by heat treatment up to 10 hours. Crystal structures were analyzed by X-ray powder diffraction and high resolution electron microscopy, and superconducting properties were determined by resistivity and DC susceptibility measurements. T_c increases with increasing number of Cu layers up to n = 4, where it turns down.
