A new {open_quotes}1201{close_quotes} mercury-based cuprate with HgCe mixed layers: The oxide Hg{sub 0.4}Ce{sub 0.5}Cu{sub 0.1}Sr{sub 2-x}La{sub x}CuO{sub 4+{delta}}

A new {open_quotes}1201{close_quotes} mercury cuprate Hg{sub 0.4}Ce{sub 0.5}Cu{sub 0.1}Sr{sub 2-x}La{sub x}CuO{sub 4+{delta}} characterized by Hg,Ce and Sr,La mixed layers has been isolated. The electron diffraction study evidences a quadruple cell with regard to the classical 1201 cell resulting in a doubling of the b and c parameters. The origin of the superstructure is assumed to be due to an ordering between mercury and cerium within the same layers as observed in mixed Hg,Pr layers. XRD calculations and HREM observations support this point of view. Order-disorder phenomena and extended defects observed in these compounds and described and discussed. No superconductivity has been detected.
