N2 - Recently, tremendous efforts have been devoted to the deposition of high performance superconducting YBa 2Cu 3O 7 (Y123) films for second-generation coated conductors. A few recent studies have shown that thin films of other rare-earth superconducting materials REBa 2Cu 3O 7 (RE = Nd, Sm, Eu...) exhibit a much better surface morphology than Y123. Here, we show our systematic studies of Eu 123 films deposited by pulsed-laser deposition. The lattice parameter and the surface of the substrate play major roles in determining the superconducting properties of single layer Eu 123 films. However, such restrictions are substantially relaxed, and a significant improvement in the superconducting properties, such as superconducting transition temperature and critical current density, has been observed, when another ultra-thin superconducting layer is inserted between the substrate and the Eu 123 film.
