ABSTRACT
An all chemical route has been used to produce substrates—nanostructured by self-assembled oxide nanoislands—and to grow YBa2Cu3O7-x (YBCO) films on top. A great increase in the superconducting properties has been observed at high temperatures and magnetic fields parallel to the YBa2Cu3O7-x c-axis. The vortex pinning properties and the defects induced in the YBa2Cu3O7-x matrix have been investigated. We show that extended defects along the c-axis, induced in the YBCO matrix by the interfacial nanostructures, lay at the origin of the improved performances.

    Pulsed laser deposition (PLD) method with a substrate heating system enabled us to obtain Sm-Co thick film magnets with the thickness of several ten microns. With increasing a substrate temperature from 673 to 1073 K, the direction of anisotropy changed from in-plane to perpendicular one. The...

    ZnO thin films were deposited by pulsed laser deposition (fluence 2.2 J/cm²) in vacuum on different substrates kept at room temperature. This temperature allowed for fast film growing, however the as-prepared films had low transparency. To improve this optical property, keeping up at the same...
