| 内容記述 | By replacing Y with several kinds of rare-earth elements (RE’s), new members of high-temperature superconductor related cuprates, (Pb, Cu)Sr2(RE, Ca)Cu2Oz (z ≈ 7, RE: Sm, Eu and Gd), are successfully prepared in a single-phase form. Chemical formula of these compounds proves to be (Pb(1+x)/2Cu(1−x)/2)Sr2(RE1−xCax)Cu2Oz, which is completely same as that of (Pb, Cu)Sr2(Y, Ca)Cu2Oz. Single phase samples are obtained for x = 0–0.5 in the cases of RE = Sm and Eu while in the case of RE = Gd, those are obtained for x values up to 0.4. Solubility of Ca in the RE site varies in accordance with RE species and seems to strongly depend on its ionic radius, i.e., large RE3+ results in large solubility. In addition, formation process of the present compounds is discussed based on the results of X-ray diffractometry, differential thermal analysis and scanning electron microscopy. | |||||
