Development of YBa₂Cu₃O_7−δsuperconducting thick film on Ba₂SmSbO₆substrate material synthesised by combustion technique

Nanoparticles of samarium barium antimonate (Ba2SmSbO6), a complex perovskite has been synthesised using an auto-ignition combustion process. The nanoparticles thus obtained have been characterised using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The particle size of the as-prepared powder was in the range 50–110 nm. Superconducting YBa2Cu3O7− δ material was synthesised through solid-state route and the thick film of YBa2Cu3O7− δ material was fabricated by dip-coating on Ba2SmSbO6 substrate. The prepared samples were subjected to various studies such as XRD, TEM, scanning electron microscopy, and resistivity measurement and the obtained results are presented and discussed.
