摘要：
Superconductivity with a maximum T(c, zero) of 58 K for x > 0.75 has been observed in a nominal starting composition, Th(x)Tl2Sr2Ca2Cu3O(v). X-ray data show that the 1212 phase gets stabilized due to part substitution of Th at the Tl-site for x greater-than-or-equal-to 0.25; however, T(c) is low for x < 0.75.
