THE STRUCTURAL CONSEQUENCES OF CHARGE DISPROPORTIONATION IN MIXED-VALENCE IRON-OXIDES .1. THE CRYSTAL-STRUCTURE OF SR2LAFE3O8.94 AT ROOM-TEMPERATURE AND 50-K
The crystal structure of the averaged-valence phase of the rhombohedrally distorted perovskite Sr2La Fe3O8.94 has been refined from neutron powder diffraction data collected at room temperature (space groupR3-c, a = 5.4712Å, α = 60.09°). All iron sites are identical. The crystal and magnetic structu...
