Crystal structure, thermal expansion, and electrical properties of layered oxides LnBa(Fe, Co, Cu)2O5 + δ (Ln = Nd, Sm, Gd)

  • A. I. Klyndyuk
  • E. A. Chizhova


LnBaFe0.5Co0.5CuO5 + δ and LnBaFeCo0.5Cu0.5O5 + δ solid solutions (Ln = Nd, Sm, Gd) are synthesized by the solid-phase method; their structural parameters and oxygen nonstoichiometry are determined; and the thermal expansion, conductivity, and thermal emf of these crystals are investigated. The thermal expansion coefficient of sintered ceramics and its electric transport parameters are calculated. The influence of the nature of rare-earth elements (REE) and 3d metal on the crystal structure, oxygen nonstoichiometry, and physicochemical properties of layered oxides LnBa(Fe, Co, Cu)2O5 + δ are analyzed.
