Topochemically Reduced Iridium Double Perovskite Phases
We propose to collect neutron powder diffraction data from Sr2FeIrO4 and Sr2CoIrO4 at room temperature to determine their anion-deficient crystal structures. We also propose to collected data at low temperature to determine their magnetically ordered structures. Magnetisation measurements indicate the two phases should be formulated as Sr2M(II)Ir(II)O4 (M=Fe, Co) and as such they represent the first examples of Ir(II) in an extended oxide phase.
