Abstract In the present work, high-rate epitaxial growth for superconducting YBa 2 Cu 3 O 7- δ (YBCO) films on substrates of LaMnO (LMO)/IBAD-MgO/Y /Al /Hastelloy is achieved by fluorine-free metal organic deposition (FF-MOD) rapidly switching partial oxygen pressure ( p ) at a fixed temperature. Further investigation into effects temperature and phase transition YBCO elucidates that mode microstructural characteristics studied films. BaMnO heterogeneous particles are observed in localized...
The preparation of YBCO superconducting films by using metal organic chemical deposition (MOD) involves low-temperature pyrolysis and high-temperature treatment. former process generally requires the introduction water vapor other gases. study on in a low vacuum environment non-carrier gas atmosphere has never been reported. In this work, we explored scheme with simple Argon decompression carrier-free atmosphere. effects heating rate microstructure were investigated, treatment temperature...
