摘要：

By annealing the (Bi1-xPbx)2Sr2CaCu2Oy superconductor (2:2:1:2 phase) with x=0.2 in the absence of oxygen, a high-Tc value of 98.5 K was observed. The lattice of this superconductor was revealed to be monoclinic. The formation of this superconductor with an unexpectedly high Tc value for the 2:2:1:2 phase is difficult to explain simply by consideration of the optimum carrier concentration, and it is likely correlated with the structural transformation of the superconductor. © 1990 The American Physical Society.
