Fabrication of double-layered ribbons from cuprate superconductor and silver by melt spinning
Abstract
Double-layered ribbons of superconducting oxides/silver were prepared in situ by melt spinning technique from superconducting Bi-Sr-Ca-Cu-O or Y-123, and silver. These as-processed composite ribbons were found to possess metastable structures and were not superconductive. The ribbons were subsequently annealed at 935 C in oxygen in order to restore their superconductivity. The oxygen-annealed composites exhibit a superconducting transition temperature higher than 90 K.
