Abstract

High quality melt-processed (Sm_0.33Eu_0.33Gd _0.33)Ba₂Cu₃O_7-δ superconductors were grown and microstructural origin of their distinguished superconducting performance was investigated by atomic force microscopy (AFM), transmission electron microscopy (TEM) and the field dependent superconducting transition performed with SQUID. A nanoscopic periodic array of chemical composition was unveiled. This novel structure acted as δT_c -style pinning centers.
