Preparation of YBCO Thin Films by Metal Organic Deposition Method

Abstract:

Due to its high in-field superconducting performance, high irreversible magnetic field, low AC loss and high transition temperature, YBa₂Cu₃O_7-x (YBCO) has been taken as a hot research object. Well-oriented La_0.4Sr_0.6TiO₃(LSTO) thin films were prepared on the biaxially textured Ni-W alloy substrates by metal-organic deposition (MOD) method which could used for YBCO coated conductor. The homogeneous and stable precursor solution was prepared by Y, Ba and Cu acetates and deposited on LSTO/Ni-W composite structure by spin-coating method. YBCO films were obtained after heat treatment. Effect of thermal decomposition time on YBCO films was discussed,and the results showed that the proper time of organic decomposition was 3h at 400°C.
