Abstract
Bimetallic oxide nanocrystals with perovskite structure and 2-10 nm in diameter were synthesized via microwave-assisted heating of bimetallic alkoxide precursors, stabilized in polar solvents and added to the YBCO precursor solution. Superconducting YBCO nanocomposite films deposited on LaAlO3 single crystal substrates with 300 nm thickness and Jc of around 5 MA/cm² were obtained. These nanocomposites showed a smoother decay of the Jc with increasing magnetic field and the pinning force was increased by a factor of 4-5 compared to undoped samples. The challenging upscaling of these results to long industrial tapes was carried out as a part of the Horizon2020 project SynFoNY (www.synfony.eu). Different types of coated conductor nanocomposites were deposited for the first time in full-CSD process in up to 100 m long tapes reaching high self-field currents at 77 K comparable to undoped commercial tapes and showing a reduced decay of the Jc with an increasing magnetic field.
