Abstract

Microstructure of (Nd, Eu, Gd)Ba₂Cu₃O_7-δ (NEG-123) samples with (Nd, Eu, Gd)₂BaCuO₅ (NEG-211) particles were observed by transmission electron microscopy. High-resolution electron microscopy observation demonstrated that the density of microstructural defects was small around the NEG-211 secondary phase particles. Furthermore, the 123/211 interfaces were found to be very clean and sharp. Chemical compositional analysis of the submicron secondary phase particles revealed that these fine particles are not composed of NEG-211 but Eu₂BaCuO₅ (Eu-211) or Gd₂BaCuO₅ (Gd-211).
