High Critical Temperature Superconductor Substrate and Buffer Layer Compounds, A2MeSbO6 (Where A=Ba and Sr; and Me=Sc, In and Ga).
Abstract
Compounds in the series A2MeSbO6, where A=Ba, Sr, and Me=Sc, In, and Ga, have been used as substrate buffer layers with YBa2Cu3O7-x thin films. These materials were prepared by solid-state reaction of the oxides and carbonates. The compounds are ordered perovskites except for Ba2InSbO6. All compounds are cubic except Sr2ScSbO6 and Sr2GaSbO6 which are pseudo-cubic, tetragonal. Dielectric constant and loss tangent are reported for each bulk compound. Herein is described the successful deposition of thin films A2MeSbO6 on (100) MgO and A2MeSbO6/(001) YBCO/(100) MgO by pulsed laser ablation.
