摘要:
The present invention relates to a nanostructured superconducting material of type REBa 2 Cu 3 O 7 , where RE=Rare Earth or yttrium, comprising two phases, a principal matrix of REBa 2 Cu 3 O 7 and a secondary phase of BaZrO 3 , CeO 2 , BaSnO 3 , BaCeO 3 , SrRuO 3 , La 1-x M x MnO 3 (M=Ca, Sr, Ba), RE 2 O 3 and/or RE 2 Cu 2 O 5 . The secondary phase is distributed at random within the matrix in such a way that it provides a high density of nanometric defects, thereby increasing the capacity for effectively anchoring the vortices. Another subject of the invention is the procedure through which these superconducting materials are produced.
