Enhancement and elucidation of flux pinning in doped Bi-Sr-Ca-Cu-O high temperature superconducting single crystals. The proposed project aims to study the effects of elevated doping on the intrinsic electromagnetic properties of Bi-Sr-Ca-Cu-O high temperature superconducting (HTS) single crystals grown by two-dimensional and spiral-growth mechanisms with a particular focus on structure, conductivity and thermal neutron irradiation. Studies of the relationship between microstructures, anisotropy and flux pinning will lead to a better understanding of the pinning behaviour of Bi-based HTSC. The outcome will be better methods for introducing suitable pinning centres into Bi-based high temperature superconductors.
