摘要	The electrical, magnetic and magnetoresistance properties of polycrystalline Sr2Fe1-xCoxMoO6 compounds with x = 0.0, 0.05, 0.15 and 0.25 were investigated. With increasing Co content, both the degree of cationic order and the saturation magnetic moment per formula unit of these compounds increase, while their resistivity decreases monotonically and exhibits an enhanced metallic behaviour for x >= 0.15. The low-field magnetoresistance was greatly enhanced at x = 0.15, and the field dependence of magnetoresistance for x >= 0.15 almost saturates above 1.5 T. These results can be well explained by the change of magnetic structure of Sr2FeMoO6 after replacing partial Fe ions by Co ions. The enhanced metallic behaviour and low-field magnetoresistance also suggest a great application potential in spin electronic devices.
