Abstract

Nd2-xCexCuO4 (x = 0 to 0.15) thick films were grown directly on LaAlO3 substrates and surface-oxidized Ni tapes by fast liquid-phase processing methods. The films had a smooth surface and a very good biaxial texture, with the full width at half-maximum equal to 0.8° and 5° on LaAlO3 substrates and surface-oxidized Ni tapes, respectively. Films of thickness of 5-15 μm were grown at rates in excess of 2 μm/min. Nd2-xCexCuO4 has a good lattice and thermal-expansion match to rare-earth Ba2Cu3O7-δ (REBCO), minimum reaction with the high-temperature CuO:BaO solutions, and is nonpoisoning to superconductivity. It is an ideal buffer for liquid-phase expitaxy processing of REBCO thick films.
