Interrelation among superstructural ordering, oxygen nonstoichiometry and lattice strain of double perovskite Sr2FeMoO6−δ materials

Double perovskite ceramics Sr 2 FeMoO 6−δ having different amount of antisite disordering and oxygen content are prepared by the solid-phase reaction method using SrFeO 2.52(3) and SrMoO 4 initial reagents. X-ray and neutron diffraction techniques are used to estimate a modification in the structura...
