Pr1−xCaxBa2Cu3O7−δ(x ≈0.5) thin films have been grown on SrTiO3 and YSZ substrates by the pulsed laser ablation. The substrate temperature dependence of orientation and superconducting poperties were systematically studied. Good quality c and a-axis orientated films can be obtained on SrTiO3 via changing the substrate temperature solely. On YSZ, films with good c-axis orientation can be grown, ...

It is of fundamental importance to establish whether there is a limit to how thin a superconducting wire can be, while retaining its superconducting character—and if there is such limit, to understand what determines it. This issue may be of practical importance in defining the limit to miniaturization of superconducting electronic circuits. Recently, a new fabrication method, called molecular ...
