“…[1]. There are many methods by which we fabricate YBCO coated conductors, including pulsed laser deposition (PLD), dc/rf-sputtering, E-beam co-evaporation, molecular beam epitaxy (MBE), chemical vapor deposition (CVD), metalorganic chemical vapor deposition (MOCVD), solvent-intogel (SIG) and metal-organic deposition (MOD) [2][3][4]. Of these methods, TFA-MOD (metal-organic deposition using trifluoroacetates) process is a non-vacuum, liquid-based, ingredients easily controlled and cost-effective method for depositing thin films.…”

The Sm-doping YBCO films, Y 1−x Sm x Ba 2 -Cu 3 O y and Y 1 Sm x Ba 2−x Cu 3 O y (x = 0.1, 0.3), were fabricated on LAO (00l) single-crystal substrates by TFA-MOD process in order to improve the superconducting properties of YBCO films. The XRD analyses indicated that these samples have a strong c-axis texture, but the secondary phase of BaCuO 2 are found from Y 1 Sm x Ba 2−x Cu 3 O y films with Sm 3+ substitution on Ba 2+ sites. High quality surface, better in-plane and out-of-plane texture of the Sm-doping films have been obtained compared with that of the undoped YBCO film. The Y 0.9 Sm 0.1 Ba 2 Cu 3 O y films showed the highest value of T c and J c in self-field. Superconducting properties of all Sm-doping films are better than those of the pure film. These results strongly suggest that Smsubstitution on Y or Ba sites of YBCO phase is a powerful method to efficiently improve J c and introduce artificial pinning centers in YBCO films.
