摘要:
An oxide-superconductor improved so as to have a high critical temperature (T c ) comprises an oxide having a K₂NiF₄ crystalline structure similar to a perovskite crystalline structure and represented by the following formula:
(Ba x Sr z La 1-x-z )₂Cu 1-w Ag w O₄ (1-y)
wherein 0.1
(Ba x Sr z La 1-x-z )₂Cu 1-w Ag w O₄ (1-y)
wherein 0.1
