Abstract :
A preparation of YBaCuO thin film on a flexible metallic substrate with YSZ buffer layer by the KrF pulsed laser deposition (PLD) was investigated. The orientation of the YBaCuO/YSZ/Metal film was controlled by the YSZ deposition conditions. A critical temperature and a critical current density of the YBaCuO/YSZ film were 81.8 K, 1.2/spl times/10/sup 3/A/cm/sup 2/ (at 77.3 K) for Hastelloy substrate, and 79.2 K, 10/sup 2/A/cm/sup 2/ for Inconel substrate, respectively. Those low values resulted in their polycrystalline structures.<>
