- Abstract
Sr2CoMoO6 and Sr2CoMoO6-δ ceramics have been obtained by solid state reaction in air and in a H2/N2 gas mixture. At room temperature, as shown by X-ray diffraction, both compounds have a tetragonal perovskite-like structure with doublet unit-cell parameters, space group I4/m, with a = 5.5575, c = 7.9342 in Sr2CoMoO6 and a = 5.5683 and c = 7.9395 in Sr2CoMoO0.95. The latter contains small traces of Co and SrCoO2.61, with an almost expansion. The magnetic susceptibility indicates that Sr2 CoMoO6 is an antiferromagnet with TN = 37 K. The magnetization was found to be the same in both samples, while the electric properties, originating from the oxygen content, are drastically affected.
