High Tc cuprate superconducting films, such as REBa2Cu3O7-x (RE=Y, Sm, Gd), REBa2Cu4O8 (RE=Y, Yb),(Hg, Re)Ba2CaCu2O6+x, (Hg, Re)Ba2Ca2Cu3O8+x, Bi2Sr2CaCu2O8 and Bi2Sr2Ca2Cu3O10, have been studied based on “atomic level control” including lattice strain control, carrier control, and nanostructure control, in order to simultaneously improve critical temperature Tc, irreversibility field Birr, and critical current density Jc of the films. We successfully fabricated high-performance cuprate superconducting films with higher Tc, Birr, and Jc on IBAD-MgO substrates.
