The influence of synthesis conditions on structural and magneto-transport properties of Sr2FeMoO6-δ
Abstract
It is shown, that superstructural ordering of Fe3+ and Mo5+ cations and magneto-transport properties of Sr2FeMoO6-δ strongly depend on synthesis condition. Using SrFeO3 and SrMoO4 precursors as initial reagents for synthesis and performing additional reduction annealing increase superstructural ordering up to 92% and magnetoresistance up to -21 % (Т = 15 К, В = 8 T). Increasing pressure at pressing up to P = 5 GPa leads to decreasing resistivity of sample and magnetoresistance to -17 % (Т = 15 К, В = 8 T).
