摘要：
It is shown for (Sr,Ca)1-yCuO2.00+z (nominal composition) superconductors fabricated under a high pressure of 5 GPa and at 930-degrees-C that, as z increases, the Meissner fraction increases from a few percent to 20% and then starts to decrease. In the X-ray powder diffraction pattern for the sample with the maximum Meissner fraction, it is obvious that the ''infinite-layer'' structure has been decomposed and a new structure becomes the major phase. It appears that the new structure is the ''0223'' structure which consists of rock-salt and the ''infinite-layer'' type blocks. This material is likely to be a new superconducting cuprate.
