Superconductivity studies on Tl-Th-Sr-Ca-Cu-O system
TL;DR: In this paper, the authors show that the 1212 phase gets stabilized due to part substitution of Th at the Tl-site forx⩾0·25; however, Tc is low forx < 0·75.

Variation in Tc, structure and oxygen content in Tl2Ba2CuO6 and their correlations
Yuichi Shimakawa,Yoshimi Kubo,Takashi Manako,Tetsuro Satoh,Sumio Iijima,Toshinari Ichihashi,Hitoshi Igarashi +6 more
TL;DR: In this article, the superconductivity and structural variations of Tl 2 Ba 2 CuO 6 (2201 compound) were studied. But the appearance of superconductivities was independent of the structural symmetry, and was strongly affected by oxygen content.

Superconducting Tl2Ba2CuO6: The orthorhombic form
TL;DR: In this paper, the structure of an orthorhombic variant of Tl 2 Ba 2 CuO 6 (Z = 4), with a superconducting onset at 90 K, has been studied using neutron powder diffractometry at 12 K (a = 5.4834(3), b =5.4586(3, c = 23.246(1) A).
