According to the conventional theory, the CuO₂ plane is considered to be the driving force of superconductivity in cuprate superconductors. However, in Pr247, the CuO₂ plane is insulating, but superconductivity is observed, suggesting that the CuO double chain drives superconductivity. In this study, we synthesize (Pr,Y)247 and show that the CuO₂ plane is superconducting, non-superconducting, and superconducting in the CuO double chain by controlling the oxygen content.
