Abstract

An oxide superconductor includes a textured superconducting material including an array of defects with a neutron-fissionable element, or with at least one of the following chemical elements: uranium-238, Nd, Mn, Re, Th, Sm, V, and Ta. The array of defects is dispersed throughout the superconducting material. The superconducting material may be the RE1 Ba2 Cu3 O7-δ compound, wherein RE=Y, Nd, La, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu; the Bi2 Sr2 CaCu2 Ox, the (Bi, Pb)2 Sr2 CaCu2 Ox, Bi2 Sr2 Ca2 Cu3 Ox or (Bi, Pb)2 Sr2 Ca2 Cu3 Ox compound; the Tl2 Ca1.5 BaCu2 Ox or Tl2 Ca2 Ba2 Cu3 Ox compound; or a compound involving substitution such as the Nd1+x Ba2-x Cu3 Ox compounds. The neutron-fissionable element may be uranium-235. The oxide superconductor may include additional defects created by fission.
