Abstract

Biaxially aligned NdGaO/sub 3/ (NGO) layers were successfully fabricated on the single crystalline substrates (STO, LAO and NiO/STO) and metallic substrate (NiO/Ni) by pulsed laser deposition (PLD) method and post-annealing process. And also, the good biaxial orientation YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) films on NGO layers were deposited by liquid phase epitaxy (LPE) method. From this work, it has been proved for the first time that NGO thin film can be used as a seed layer for the YBCO thick film deposition by LPE method. And it is clear that the NGO thin film growth process, where biaxially orientated films were deposited using PLD at room temperature followed by simple post-annealing process, is very effective for the uniform long length coated conductor production.
