Heat treatment effects on the physical properties have been investigated for Sr2FeMoO6 single crystals with double perovskite structure. We have evaluated the occupancy g of the Fe3+ ion on one sublattice of the perovskite-B site by Rietveld refinement of the synchrotron-radiation X-ray powder patterns. Both the saturation magnetization Ms and critical temperature Tc for the ferrimagnetic transition decrease linearly with g in the large-g region (g ≥ ∼0.84), but begin to deviate from the empirical relations for g ≤ ∼ 0.84. We interpreted this behavior in terms of variation of the correlation length of the spin ordering.
