Ba-Y-Cu-O Thin Films Fabricated by Dip Coating Using Concentrated Mixed Alkoxide Solution

Abstract

Superconducting oxide thin films of Ba 2 YCu 3 O x were fabricated on polycrystalline zirconia ZrO 2 -Y 2 O 3 (PSZ) substrates for the first time by a dip coating technique using an ethanol solution of highly concentrated mixed alkoxides of the component metals (0.6 mol/l). The thickness of the films prepared ranged 2.1–0.8 µm and the best sample showed T c(onset) =94 K and T c(zero) =60 K.
