Abstract
Nearly-pure 1201-type cuprate HgBa2CuO4+delta was successfully synthes ized at ambient pressure in an open system, and was characterized by p owder x-ray diffraction analyses and by resistance and ac susceptibili ty measurements. The lattice parameters are a = 3.8742(5) Angstrom and c = 9.4798(11) Angstrom, and the T-c,T-onset is up to 95 K. The resul ts of the present experiment are instructive to the understanding of t he formation mechanism of Hg-based superconductors, and thus to the pr eparation of existing Hg-based superconductors and to the search for n ew Hg-based high T-c superconductors.
