采用高压合成法，合成了单相的A-1232氧化铜，其组成为。-1232相在相邻晶面之间含有一个三层萤石结构的块体。通过射线衍射、高分辨透射电子显微镜和电子衍射证实了晶体结构。与先前已知的三层萤石层氧化铜相相比，这-1232相显示出具有大迈斯纳体积分数的完美抗磁性。超导转变温度为。
A-1232-phase copper oxide has been synthesized in an essentially single-phase form with the composition of, through high-pressure synthesis atand. The-1232 phase contains a three-layer fluorite-structured block between adjacentplanes. The crystal structure was confirmed by-ray diffiaction, high-resolution transmission-electron microscopy, and electron diffraction. In contrast to the previously known three-fluorite-layer copper-oxide phases, perfect diamagnetism with a large Meissner volume fraction was revealed for this-1232 phase. The superconductivity transition temperaturewas found at.
