发明名称 Superconductor with layer structure
摘要 A largely uniform superconducting compound having a layer structure and the overall composition Bi4(Ca,Sr)6Cu4Oapprox. 20 with an atomic ratio Ca/Sr of 1:3.5-1:6.28 is described and its three-dimensional structure is given. In addition, superconducting compounds of the formula Bi4(Ca,Sr)4+2nCu2+2nOapprox. 12+4n with n = 2-5 are described.r
