- Abstract
Ag-doped GdBa2Cu3O7−δ (GdBCO)-coated conductors are fabricated via a metal-organic process. The X-ray diffraction and scanning electron microscopy results show that the growth conditions of the GdBa2Cu3O7−δ matrix are modified, resulting in less a-axis growth and much smoother surface morphology and finally giving rise to much improvement of superconducting performance in a wide range of processing parameters. The orientation behavior and mechanism of Ag-doped GdBCO films are investigated. To reasonably explain the orientation behavior of Ag-doped GdBCO films, a simple nucleation model for Ag-doped GdBCO is established, suggesting quasi-liquid phases are perfected by Ag. As a consequence, a-axis nucleation is suppressed and strong c-axis nucleation is achieved in a wider processing window.
