✦ Synopsis

The existence of materials of the type (Ln,Ce)2Sr2CuaOs., (Ln=lanthanide, Y), analogues of the unstable YSr~CuaO,.~, with yttrium replaced by a fluorite block, (Ln,Ce)202, have yet to confirmed by detailed structural studies. Reported here are the results of an investigation into their formation and structure which indicate the partial substitution of copper on the "Cul" sites by cerium to be necessary to stabilise the YBCO-type structure.

We report micro and macro hardness measurements made on a polycrystalline sample of YBa,Cu3()= ,. Microhardness indentations in the interior of grams revealed that this material has, in many cases, enough ductility to allow the formation of cleat" diamond marks.
