Single phase HgBa2CuO,~ samples were annealed in flowing oxygen gas or m flowing argon gas. Oxygen contents of both samples determined by iodometric titrations indicate that the samples annealed in oxygen gas and in argon gas were respectively in over-doped and in under-doped region. Both samples we

The real X' and imaginary Z" components of the AC susceptibility for a ceramic sample of superconducting HgBa2CuO4+6 have been measured at HAC = 0.1 Oe over the temperature range 80-300 K under purely hydrostatic pressure conditions. Upon cooling, a slight but sharp decrease in slope dz'/dT occurs a
We have synthesized nearly single-phase HgBa2CuO4+ ~ samples with various oxygen contents, and systematically investigated the relationship between the lattice parameters, the superconductivity transition temperature (T c) and the oxygen content determined by iodometry. Furthermore, the nominal copp
