摘要：
Samples with nominal compositions of x = 0-0.1 in (Bi(1+3x)/3Cu(2-3x)/3)Sr-2(RE1-xCax)Cu2Oz ((Bi,Cu)-"1-2-1-2"; RE: V or rare-earth element) were synthesized by a solid-state reaction method and characterized by means of X-ray diffractometry (XRD). It is confirmed that the (Bi,Cu)-"1-2-1-2" forms only when RE = Y, Dy and Ho. Single- or nearly single-phase samples are obtained for x = 0-0.05 and the Ca-free composition of this compound is determined to be (Bi1/3Cu2/3)Sr2RECu2Oz. Since ionic radii of Y, Dy and Ho are very close to each other and this seems to be an essential factor for the stability of the (Bi,Cu)-"1-2-1-2". (C) 2010 Elsevier B.V. All rights reserved.
