Crystallography at non-ambient conditions and physical properties of the synthesized double perovskites, Sr2(Co1−xFex)TeO6

We report the synthesis of double perovskite oxides Sr 2 (Co 1− x Fe x )TeO 6 obtained by solid-state reaction. The changes in the crystal structures of the samples due to iron substitution were studied using XRD, Raman spectroscopy and 57 Fe Mössbauer spectroscopy.
