dc.description.abstractPhase formation behaviors of double perovskite Sr2FeMoO6 (SFMO) derived from mechanical activation were investigated. Polycrystalline double perovskite SFMO of grain sizes in nanometer range were synthesized by heat treatment of the precursors derived from mechanical activation of SrO, Fe2O3, and MoO3 at temperatures in the range of 600°-900°C in flowing atmosphere of H2Ar. Mechanical activation at room temperature led to formation of SFMO at 700°C, which is about 200°C lower than what is required in the conventional solid state reaction. The magnetization of thus-derived SFMO increases with increasing heat-treatment temperature in the range of 700°-900°C. Similarly, its magnetoresistance ratio also increases with increasing heat-treatment temperature, which is accounted for by the elimination of insulating SrMoO4 impurity phase and enhancement in crystallinity of the double perovskite SFMO phase. © 2005 The American Ceramic Society.
