High pressure synthesis and structure of the superconducting mercury cuprates (Hg1-xMx)Ba2Can-1CunO2+2n+delta with M = C, S.
- Abstract:
-
In mercury superconducting cuprates synthesized at high pressure, partial carbon substitution on the mercury site occurs when the precursors are not absolutely carbon free. Hg-12(n-1)n samples made from carbonate-containing precursors show lower Tcs and smaller c parameter. A model of the structural arrangement of the CO3 -2 groups is proposed from neutron diffraction data and crystal-chemistry considerations. The third oxygen of the oxyanion is situated in the (Hg,C)O∂ layer and hinders the ...
