Abstract

(Nd,Eu,Gd)Ba₂Cu₃O_y (NEG) films were prepared on LaAlO₃ single-crystal substrates by metal-organic deposition (MOD) using fluorine-free solutions of metal 2-ethylhexanates (2-EH) or metal naphthenates (MN) with a small amount of trifluoroacetic acids (TFA) added. The addition of TFA to fluorine-free solutions lowered the growth temperatures, promoted crystal growth, and improved the superconducting properties of NEG films. This was similar to the effects observed on the growth of superconducting films by TFA-MOD using metal-trifluoroacetates. We report the successful growth of NEG films with T_c of 92.6 K and J_c of 0.36 MA/cm² without introduction of water vapor.
