Abstract
Ultra-fine MgO particles were doped into Bi-2223 precursor powder. The effe ct of MgO doping on flux pinning properties of Bi-2223/Ag tapes was investi gated. At 77 K, a J(ct) of 33.6 kA/cm(2) in self-field, and 11.2 kA/cm(2) a t 0.1 T (H/c-axis) has been achieved in the 1 wt% MgO doped samples.
