Abstract
A new superconducting material composed mainly of compound oxide represented by the general formula: EQU Tl.sub.h Ca.sub.j .alpha..sub.k(1-y) .beta..sub.ky Cu.sub.m O.sub.n wherein PA1 ".alpha." represents Ba or Sr; PA1 ".beta." represents any one of elements selected from a group comprising Na, K, Rb and Cs; PA1 "h", "j", "k", "m" and "n" are the atomic ratios each satisfies the following range: PA2 1.ltoreq.h.ltoreq.3, 1.ltoreq.j.ltoreq.3, 1.ltoreq.k.ltoreq.3, PA2 2.ltoreq.m.ltoreq.4 and 5.ltoreq.n.ltoreq.15 and PA1 "y" is a number which satisfies a range of 0.05.ltoreq.y.ltoreq.0.8.
