Abstract

The structure, magnetic properties and Mössbauer effect on Sr2Fe1 − xMxRe1 − yM′yO6 (x = 0, 0.1; y = 0, 0.1; M = Sc; M′ = Nb) phases with partially ordered double perovskite structures are presented. The Nb and Sc substitutions affect the magnetisation values but the Tc values remain unaltered around 400 K. Mössbauer analysis shows high spin Fe3+ ions, except for Sr2FeReO6, which shows a mixed valence state at high temperatures.
