Superconducting vortex physics has been a topic of interest since the discovery of the oxide high temperature superconductors (HTS). Two driving forces are behind this interest, on the one hand the attractive new physics and on the other the pursuit of technological uses. The complex vortex phenomena in oxide HTS arise from the strong influence of thermal fluctuations, which is a consequence...
REBCO wires with artificial pinning centers (APCs) are known to have extremely high Jc at low temperatures and high magnetic fields. Although understanding of the behavior of Jc when tilting the applied magnetic field from the wire surface is still insufficient, information on the angular dependent Jc is very important in coil design. In current REBCO wires, nanorods are often used for APCs...
Engineered nanoscale defects within REBa2Cu3O7-δ (REBCO) based 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 Jc via controlled introduction of various types of nanoscale defects ranging from simple rare-earth oxides and Ba-based perovskites to double...
