Substrate/Buffer Layer Compounds in the Calcium Antimonate System for Growth of Epitaxial YBCO Films.

Abstract

Using pulsed laser deposition (PLD), epitaxial thin films of Yttrium-Barium-Copper-Oxide (YBCO) have been grown on films of compounds in the calcium antimonate system, Ca2MeSbO6, where Me=Al, Ga, Sc, In, Y and La. Bulk targets of compounds were prepared from precursor oxides and carbonates using solid state reaction at temperatures between 1400 and 1500 deg C. Epitaxial relationships were determined from x-ray diffraction data. All antimonates investigated demonstrated (001) epitaxy and should support (001) growth of YBCO. Dielectric constants and losses of bulk samples were measured using cavity perturbation techniques at x band. As reported, all antimonates exhibit low dielectric constants and low losses.
