摘要:
An oxide-superconductor improved so as to have a high critical temperature (T.sub.c) comprises an oxide having a K.sub.2 NiF.sub.4 crystalline structure similar to a perovskite crystalline structure and represented by the following formula:(Ba.sub.x Sr.sub.z La.sub.1-x-z).sub.2 Cu.sub.1-w Ag.sub.w O.sub.4(1-y)wherein 0.1
