【 摘 要 】
Engineered nanoscale defects within REBa2Cu3O7-δbased coated conductors are of great interest for enhancing vortex-pinning, especially in high-applied magnetic fields. We have conducted extensive research to optimize vortex-pinning and enhance Jcvia controlled introduction of various types of nanoscale defects. This paper provides a summary on how density, morphology, and composition of these engineered nanoscale defects affects vortex-pinning in different field and angular regimes in the temperature regime of 5K-77K. It is shown that certain nanodefect configurations that provide the best performance at high-operating temperatures also result in the optimal properties with record values of the critical current density and the pinning force at low operating temperatures and high-applied magnetic fields.【 预 览 】
