Abstract:The influences of processing parameters on phase purity and texture, surface morphology and superconducting properties of YBCO films fabricated by TFA-MOD method were discussed. These films prepared under optimum conditions have pure c-axis texture and are good in-plane texture with Tc of 90K and Jc of 15000A/cm2 at 77K in self-field.
Key words: YBCO; TFA-MOD; textured Ag; ultrasonic spray pyrolysis; coated conductor
