摘要
In order to lower the production costs of coated conductors based on the ion-beam assisted deposition (IBAD) and pulsed laser deposition (PLD) method, we examined a single-buffered architecture (REBCO/IBAD/Hastelloy) without a second buffer layer of CeO2. While all samples exhibited similar degrees of the textures, transport current properties were found to be strongly dependent on the REBCO layer and IBAD template materials. With a structure of Ag/PLD-GdBa2Cu3O7/IBAD-Gd2Zr2O7/Hastelloy, we obtained critical currents of 165 Amps (0.8 mu m-thick) and critical current densities of 3.4 MA/cm(2) (0.4 mu m-thick) for short-piece samples in standard four-probe de measurements.
