Abstract
With iodine vapour treatment of various single crystals of Bi-Sr-Ca-Ln(Rare earch element)-Cu-O system, the stage-1 iodine-intercalation compounds of Bi2(Sr,Nd)2CuOy(2201), Bi2Sr2(Ca,Gd)Cu2Oy or Bi2Sr2CaCu2Oy(2212) and Bi8SrCaO14 have been prepared. x-ray diffraction and transmission electron microscope analysis indicate that iodine layer of thickness 3.2～3.5Å is formed between two Bi2-O2
