X-ray diffraction study of the GdMIICoO3.5 (MII = Mg, Ca, Sr, Ba) cobaltites

Abstract

Four compounds with the general formula GdMIICoO3.5 (MII = Mg, Ca, Sr, Ba) have been prepared for the first time by high-temperature solid-state reactions between gadolinium(III) oxide, cobalt(II) oxide, and alkaline-earth carbonates. Their crystal class and unit-cell parameters have been determined by X-ray diffraction.
