| Popis: | The polycrystalline Sr 2 FeMoO 6- x S x (0.0 ≤ x ≤ 0.4) series were synthesized. The structure of Sr 2 FeMoO 6- x S x 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 4 e and 8 h 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. |
