Popis:	The magnetic and electric properties of the Sr 2 FeMoO 6 compound produced under different preparation conditions were studied. Depending on the preparation condition, a strong variation in the nonmagnetic SrMoO 4 impurity content was found, which in turn determined the metallic or semiconducting behavior of the resistivity of the Sr 2 FeMoO 6 compound. There was also evidence that SrMoO 4 played a crucial role in modifying the low magnetic field intergrain tunneling magnetoresistance in Sr 2 FeMoO 6 . In addition, we have established a simple method to prepare the single phase Sr 2 FeMoO 6 polycrystals.
