Abstract:
A Chemical spray deposition process with mixed nitrate solution as source was developed to prepare thin films of Ba-Y-Cu oxide on sapphire substrate. By adjusting the source composition and deposition conditions, we have successfully obtained the films in thickness of 2–15μm with essentially orthorhombic Ba 2 YCu 3 O 7 phase. The films behave super conducting transition with onset above 90K and zero resistance at 68.4K to date. It is believed that the tails in the resistance transition can be improved by searching proper heat treatment and using suitable substrates such as ZrO 2 and SrTiO 3 .
