Abstract
A composite superconductor SiO2/YSZ/CeO2/YBa2Cu3Oy with a critical current density of 7 × 104 A/cm2 has been prepared by laser ablation. Small hills enriched in copper and oxygen on the surface of the deposited films have been detected using scanning electron microscopy. A grain structure (sizes of 0.2–0.3 μm) and a system of twins ~400 Å in width have been detected in the superconducting film using transmission electron microscopy. Such a structure and high (001) texture of the film provide the noted critical current density.
