Abstract
Full text: Materials based on the basic perovskite structure, CaTiO{sub 3{sub {delta}}} show a vast range of physical properties, including high temperature superconductivity and colossal magneto-resistance. Here a structural study of the M{sub 1-x}Sr{sub x}CoO{sub 3-{delta}} family of oxides, where M is Y{sup 3+} or a lanthanide ion and x = 2/3 is presented. The samples were synthesized using sol-gel methods and sintered in air. The solid solution range is outlined, both in terms of x and M. The existence of supercell reflections is demonstrated, and electron diffraction and synchrotron and laboratory X-ray diffraction shows the structure to be pseudo-tetragonal, with space group Cmmm and lattice parameters approximately 2{radical}2a, 2{radical}2a, 4a where a is the basic perovskite lattice vector.
