| dc.description | The effects were studied of surface buffer layers, a sputtered gold or platinum film and/or a screen-printed Y<sub>2</sub>BaCuO<sub>5</sub> (211) layer, on the microstructure, preferred orientation and superconducting transition of YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> (123) films, grown by a melt method without crucible on polycrystalline alumina substrates. The degree of (00L) preferred orientation (DPO) reached 89% as Pt buffer alone was used, but this was without a superconducting transition. A combined 211 layer on a sputtered metal layer resulted in films with T<sub>c-zero</sub> of above 55 K, smoother film surfaces and DPO of 44%. The growth of preferred orientation is attributed to an inhomogeneous (00L) nucleation effect during solidification. Reduced surface cracks and better connection among crystallites of the film grown on a combined buffer layer are responsible for the measurable superconducting transition. |
