Title

Microstructural control and superconducting properties of YBa₂Cu₃O₇₋ₓ melt textured single crystals

Keywords and Phrases

Critical current density; Y123 superconductors

Abstract

"The high temperature superconductor has great potential for practical applications such as superconducting energy storage systems. Since the levitation force, required specifically for these applications, largely depends on the critical current density and loop size of the superconducting current, large-sized single crystals with high critical current density are desired. To achieve the goal in fabricating YBa₂Cu₃O₇₋ₓ(Y123) samples suitable for the applications, detailed and systematic studies are required to gain further understanding of the crystal growth and flux pinning mechanisms. This research is aimed at constituting a contribution to the knowledge base for the Y123 high temperature superconductor field by extending the study of processing conditions involved in controlling the microstructure of the Y123 superconductors for the enhancement of crystal growth and superconductor properties"--Abstract, leaf v.
