Abstract:
Electron-doped double perovskite compounds
(Sr2 La )FeMoO6 ( = 0 0 0 5 0 7) were synthesized by
combustion synthesis using Oxalic acid dihydrazide as fuel. There
is an increase in Curie temperature ( ) with La substitution up
to a value of 172 C for (Sr1 3La0 7)FeMoO6. The compound
(Sr1 5La0 5)FeMoO6 with increased compared to the undoped
sample, exhibits a intergrain magnetoresistance of about 3% in
a field of 0.1 T. The presence of magnetoresistance in La-doped
samples prepared by combustion synthesis is due to the increased
number of intergrain tunnel barriers.
