Abstract

The iron oxycarbonate Sr₄Fe₂O₆CO₃ is reported. The crystal structure and magnetic order were determined by magnetic susceptibility, powder neutron diffraction, and neutron scattering studies. The structure is tetragonal between 10 and 400 K (I4/mmm, a = 3.88907(4) Å and c = 27.9818(4) Å at 295 K), and is related to a 4:3 type Ruddlesden-Popper phase with CO₃ plaques in place of the middle layer of transition metal octahedra. The three-dimensional magnetic ordering transition temperature is 361 K. The magnetic order is antiferromagnetic within the FeO₂/SrO/SrO/FeO₂ blocks and ferromagnetic between blocks.
