Abstract
Two different oxides with the same 1:1:2 cationic ratio have been obta ined in the Sr-Ca-Cu-O system by applying different pressure synthesis conditions. Selected area electron diffraction (SAED) and high resolu tion transmission electron microscopy (HRTEM) show these phases formed by new different superstructures. Tentative structural models based o n the two-dimensional ordering of Sr and Ca atoms are proposed.
