摘要：
The polycrystalline Sr2FeMoO6-xSx (0.0 <= x <= 0.4) series were synthesized. The structure of Sr2FeMoO6-xSx is assigned to tetragonal system with space group I4/mmm. The cell volume decreases with x from 0.0 to 0.3, then, increases with x from 0.3 to 0.4. S doping leads the oxygen/sulfur at 4e and 8h positions to movement away from Fe and to displacement toward Mo, respectively. The M-S at room temperature increases with degree of order of Fe and Mo ions. The electrical resistivity for studied samples exhibits a semiconductor-like behavior. The resistivity decreases with S doping. The electrical transport behavior is mainly dominated by electron-electron interactions except x = 0.4 in 0.0 magnetic field. (c) 2017 Elsevier Masson SAS.
