摘要：

The new YBaCuO superconductors are synthesized by using the standard solid-state reaction method as compositions of Y5-6-11, Y7-9-16,Y358, Y5-8-13, Y7-11-18, Y156, Y3-8-11, and Y13-20-23, where the numbers indicate Y, Ba, and Cu atoms respectively; all show the Meissner effect at 77 K. The resistivity measurements used by the four-probe method have shown the highest T (c) onset is 94 K. The XRD spectra are shown and they have a similar crystalline structure as Y123 and Y358 materials with some impurities peaks.
