A. Tauber et al., HTSC SUBSTRATE AND BUFFER LAYER COMPOUNDS, A(2)MESBO(6) WHERE A=BA,SRAND ME=SC,IN AND GA, Physica. C, Superconductivity, 256(3-4), 1996, pp. 340-344
Compounds in the series A(2)MeSbO(6) where A = Ba, Sr and Me = Sc, In
and Ga have been used as substrate/buffer layers with YBa2Cu3O7-delta
thin films. These materials were prepared by solid-state reaction of t
he 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 tang
ent are reported for each bulk compound. Herein is described the succe
ssful deposition of thin films A(2)MeSbO(6) on YBCO, A(2)MeSbO(6)/(001
) YBCO/(100) MgO by pulsed-laser ablation.
