The influence of successive sintering treatments on the structural, magnetic and electric properties of high ordered Sr2FeMoO6 (SFMO) samples belonging to the same starting batch was investigated. The solid-state synthesis conditions influence the microstructure of the samples and the Fe/Mo order. Successive sintering treatments with intermediate grindings improve the saturation magnetization (3.8μB) which became close to the ideal value (4μB) and the low field magnetoresistance (LFMR) as a consequence of microstructural changes. Above the Curie temperature the evolution of effective magnetic moment values depicts the presence of mixed valency states: FeII/MoVI and FeIII/MoV where the contribution of FeII/MoVI configuration is favoured by the enhancement of Fe/Mo order during successive sintering treatments.
