Abstract
At 1200°C in air, the solid solubility of Mo in Sr(Fe,Mo)O3−x (SFM) does not exceed 15 mol.%. SFM is in equilibrium with most of the compounds of the system SrO–Fe2O3–MoO3. The oxygen content, the a axis parameter, and the resistivity of SFM increases with increasing Mo content. The oxygen analysis of SFM indicates mixed valent states of Fe (Fe3+/Fe2+) and or Mo (Mo6+/Mo5+). Magnetoresistance was not observed in SFM samples.
