The resistance-pressure and capacitance-pressure relationships for double perovskite compound Sr2FeMoxNb1-xO6 (x=0, 0.3) have been studied in the pressure range of 0~20 GPa using a diamond anvil cell at room temperature. The experimental results indicate that Sr2FeNbO6 undergoes a structural transition at about 7.5 GPa while Sr2FeMo0.3Nb0.7O6 at about 2.8 GPa. According to the analysis of energy dispersive X-ray diffraction with synchrotron radiation, these are considered as electronic structure transitions caused by high pressure.
