Dip-coated YBa2Cu3O7−x films on Ag substrate by MOD method

The metal organic deposition (MOD) process of YBa2Cu3O7-x (YBCO) using metal trifluoroacetates (TFA) precursors is considered to be a strong candidate as a low cost fabrication process in coated conductors since the TFA-MOD process is a non vacuum process and can provide high J(c) films. Metal organic deposition using trifluoroacetates (TFA-MOD) with dip coating was applied for the preparation of YBCO films. The thickness of films increases with the withdrawal speed of substrates. In this work, a triple coated film was fabricated on Ag {110}< 110 > textured polycrystalline substrate by optimizing the condition of heat treatments in the multi-coating method. The YBCO films have J(c) value of 15000A/cm(2) (77K, 0T) measured by the four-probe-method.
