Oxygen vacancy ordering in SrFeCoO perovskite material.

SrFeCoO was synthesized by a solid-state reaction. Its structural study at room temperature using conventional X-ray as well as neutron powder diffraction, electron diffraction and high-resolution transmission electron microscopy is presented. An oxygen-vacancy ordering related to the "314" model known for the SrYCoO oxide is proposed despite neither an A-site ordering nor an A-site mismatch.

Effect of Co Substitution on the Crystal and Magnetic Structure of SrFeO: Stabilization of the "314-Type" Oxygen Vacancy Ordered Structure without A-Site Ordering.

A study of the structure-composition-properties correlation is reported for the oxygen-deficient SrFeCoO (x = 0.1-0.85) materials.
