High Performance of YBCO Films Prepared by Fluorine-free MOD Method and a Direct Annealing Process
Chemical solution-deposited (CSD) is a cost-effective non-vacuum method for YBCO coated conductor fabrication.We developed a new fluorine-free metal-organic deposition (MOD)method with metal acetates,propionic acid and xylene as the starting materials.Using this non-fluorine MOD method,we were able to get high performance YBCO superconducting films within a shortened heat treatment time,which was reduced by at least 5 h in comparison with that for the pyrolysis-annealing non-fluorine MOD process.Superconducting property,with a critical current density (Jc) over 0.55 MA/cm2 at 77K,self-field has been obtained for 380 nm epitaxial YBCO thin films on (001) LaAlO3 single crystal substrate.Owing to the low price of starting materials and the shorter heat treatment time,fluorine-free MOD method is a very effective and cost-cutting process.
