Structure and Magneto-resistance in Nanostructured Sr2Fe1-xCrxMoO6 (0≤X≤0.3) Double Perovskite Componds

摘要：

The compounds of Fe substitution of Cr in nanotructured Sr2Fe1-xCrxMoO6 (0≤X≤0.3) double perovskite have been prepared by sol-gel method. The x-ray diffraction patterns of the samples show that the samples are in nanometer range. And the average grain size D for these samples is 39.7, 37.1, 33.4, 31.9, and 31.2nm, respectively, decreases with the increasing of Cr ion. The saturation magnetization and the magnetoresistance of the samples decrease with the increasing of Cr for the disorder defects which increase for the close ionic radii of Mo and Cr.
