Substitution effect in double perovskites, Sr(FeRe)O3 (SFRO), was studied by Mössbauer spectroscopy and magnetization measurements. The samples were prepared by a sol-gel method. The fraction of alternately ordered Fe1 for SFRO is 72%, and the magnetization measured is consistent with 3 × 0.72=2.16μB/f.u., but the saturation magnetization drops to about one third of its initial value by substituting 5% Ba for Sr. It was considered to be due to the volume expansion of the lattice and the fine grains formed, as a result of the substitution of Ba ions.
