. The micro-Raman technique is used to examine the phase purity of Sr2FeMoO6 compound in this work. It is found that the Raman spectra of Sr2FeMoO6 compound without impurity consists of the peaks at about 440cm-1 and 620cm-1. The broad peak and shoulder at 820-890cm-1 in the Raman spectra is assigned to the most common impurity SrMoO4 and some other unidentified co-existing phases, which is approved by the results of X-ray diffraction.
