摘要

type superconductor nanostructured REBa_ {2} {3} Cu_ O_ {7} (RE = Rare Earth or Yttrium) with a high density of vortices anchor centers and their method of preparation.; The present invention relates to a nanostructured superconducting material type REBa_ {2} Cu_ {3} O_ {7}, where RE = Rare Earth or yttrium, comprising two phases, a principal matrix REBa_ {2} Cu_ {3} O_ {7} and a secondary phase BaZrO_ {3}, CeO_ {2}, BaSnO_ {3}, BaCeO_ {3}, SrRuO_ {3}, LA_ {1-x} M_ {x} MnO_ {3} (M = Ca, Sr, Ba), RE_ {2} {3} O_ and / or RE_ {2} {2} O_ Cu_ {5}). The secondary phase is distributed at random within the matrix so as to provide a high density of nanometric defects in the structure of the material, increasing the capacity of effectively anchoring the vortices. Another object of the invention is the method by which these superconducting materials are obtained.
