Abstract : A series of compounds in the system A4MeSbO12, where A=Ba,Sr and ME=Li,Na and K, were prepared by solid state reaction at elevated temperature. A new form of strontium sodium antimonate (Sr4NaSb3Ol2) was prepared. The compounds that were prepared were characterized with regard to their lattice parameter, density and dielectric properties. Thin films were prepared by pulsed laser ablation deposition from dense targets, and epitaxial relationships identified between YBCO and these compounds.
