The biaxially textured ion beam-assisted deposited (IBAD)-MgO templates were successfully prepared on polycrystalline Hastelloy metal substrate with reel-to-reel system for YB2Cu3O7-delta (YBCO)-coated conductors. By the solution deposition planarization technique, amorphous Y2O3 films were coated on untreated Hastelloy substrate as the bed layer to obtain smooth, dense, and crack-free surface for subsequent IBAD-MgO deposition. The 50 m long IBAD-MgO and homo-epitaxial (epi)-MgO buffer layers deposited on Y2O3 films exhibit excellent crystallographic consistency along the scope with full width half maximum (FWHM) values of (110) Delta I broken vertical bar and (200) Delta omega in the range of 5.5A degrees aEuro6.0A degrees and 3.0A degrees aEuro3.5A degrees, respectively. To match the lattice constant of YBCO material, LaMnO3 cap layer was fabricated on IBAD-MgO templates by radio frequency (rf) magnetron sputtering with the FWHM values of in-plane and out-of-plane of 6.8A degrees and 3.7A degrees, respectively, indicating excellent biaxial texture.
