High quality melt-processed (Sm0.33Eu0.33Gd 0.33)Ba2Cu3O7-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 δTc -style pinning centers.
