Abstract
Phase relations and transport properties of undoped and La and/or Ti-doped Sr 4Fe 6O 13 have been studied. In the doped materials significant amounts of perovskite SrFeO 3− δ were formed together with SrFe 12O 19. An intergrowth on nanoscale of SrFeO 3− δ and Sr 4Fe 6O 13 was observed in the TEM for the La-doped material. The content of La was higher in the SrFeO 3− δ than in the Sr 4Fe 6O 13 phase. The electrical conductivity and chemical diffusion coefficient of undoped and La/Ti-doped Sr 4Fe 6O 13 have been measured and a defect model for undoped Sr 4Fe 6O 13 is presented. The transport properties of doped Sr 4Fe 6O 13 reflect multiphase materials mainly dominated by the perovskite phase.
