Abstract
The present-day development of YBCO nanocomposite films via a low-cost chemical solution deposition strongly focuses on the optimization of flux pinning through the addition of preformed nanocrystals. Successful fabrication of such nanocomposite films with improved pinning properties has been demonstrated on the single-crystal and long-length textured substrates. The major goal of this study is to understand how the oxygen doping level influences the critical current of YBCO nanocomposite films. The effective nanocrystals being ~10 nm in size affect the strain state and cell volume of the YBCO matrix; the two effects should result in changes of the YBCO doping state. In this contribution, we present our results on the oxygenation kinetics, which appears to be strongly affected by the presence of nanoparticles and on variation in Tc and Jc of the MOD-TFA (YBCO + BaZrO3/BaHfO3) nanocomposite films deposited on industrial CeO2/LZO/NiW substrates as function of the oxygenation conditions.
