Scattering Measurement

Complex perovskite oxides of Sr0.5(Nb0.5Ta0.5)O3 were synthesized by reassembling (SrNb2O7)2− and (Sr1.5Ta3O10)2− nanosheets followed by topochemical dehydration with heat treatment. Atomic force microscopy (AFM) images showed that the thicknesses of the (SrNb2O7)2− and (Sr1.5Ta3O10)2− nanosheets were approximately 6 nm (7 unit layers) and 4 nm (3 unit layers), respectively. Raman scattering measurement has suggested that nanosheet-processed Sr0.5(Nb0.5Ta0.5)O3 with B-site-cation ordering has a superlattice-like structure composed of alternating layers of Sr0.5NbO3 and Sr0.5TaO3 along the c-axis. Nanosheet-processed Sr0.5(Nb0.5Ta0.5)O3 with B-site-cation ordering exhibited a dielectric permittivity of 42 (1 MHz), which was lower than that of solid-state-reacted samples (65) with disordered B-site cations.

A group of complex perovskite oxides Ba2RENbO6 (RE = Yb, Er and Ho) have been synthesised and developed for their use as substrate for YBa2Cu3O7-δ superconductors. These materials have a complex cubic perovskite ( A2BB′O6 ) structure with lattice constants, a=8.3–8.5 Å. Ba2RENbO6 did not show any phase transition in the temperature range 30–1100°C. The dielectric constant and loss factor of Ba2RENbO6 are in the range suitable for their use as substrate for microwave applications. YBa2Cu3O7-δ superconductors did not show any detectable chemical reaction with Ba2RENbO6 even under extreme processing conditions. Dip-coated YBa2Cu3O7-δ thick films on polycrystalline Ba2RENbO6 substrate gave a T c (0) of 92 K and a current density of ~ 1.2 × 104 A cm-2.
