โœฆ Synopsis

We produced the HgBa2Ca2Cu308+ x (Hg-1223) superconductors by changing the composition, mercury vapor pressure and reaction temperature. We found that the high mercury pressure is essential for the formation cf the Hg-1223 phase by preventing the decomposition of HgO at low temperature. This sample was characterized by the X-ray diffraction, Auger electron microprobe, AC susceptibility and resistivity measurement.
