Abstract

Nd-Ca-Ba-Cu-O thick films with a tetragonal structure have been successfully grown on NdGaO 3 (110) single crystals by a liquid-phase epitaxy (LPE) technique using a Nd-BaCu-O powder as a solute, BaCuO 2 -CuO powder as a flux and CaO as a crucible. The films epitaxially grown at temperatures between 1173 K and 1273 K showed perfect a-axis orientated growth. The chemical composition of the grown film was found to be Nd 0.81 Ca 0.18 Ba 2.1 Cu 3.0 O y. The film showed a sharp superconducting transition with T c (onset) = 79.5 K and a transition width of 0.5 K. The a-axis orientated film showed a very smooth surface.
