An oxide superconductor includes a textured superconducting material including an array of defects, where the defects are a compound of two elements foreign to the superconductor, plus other elements native to the superconductor. The two foreign elements include one from group A and one from group B (or alternately the two foreign elements include the element uranium and one element from group C), where group A includes Cr, Mo, W, or Nd, group B includes Pt, Zr, Pd, Ni, Ti, Hf, Ce and Th, and group C includes Zr, Pd, Ni, Ti, Hf, Ce and Th. The array of defects is dispersed throughout the superconducting material. The superconducting material may be the RE1Ba2Cu3O7-delta compound, wherein RE=Y, Nd, La, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, Tb; the Bi2Sr2CaCu2Ox, (Bi, Pb)2Sr2CaCu2Ox, Bi2Sr2Ca2Cu3Ox (Bi, Pb)2Sr2Ca2Cu3Ox compounds; the HgBa2Ca2Cu3O8 and HgBa2CaCu2O6 compounds, the TlCaBa2Cu2Ox or Tl2Ca2Ba2Cu3Ox compounds and compounds involving substitution such as the Nd1+xBa2-xCu3Ox compounds.
