Popis: The single-phase Cr-doped Sr 2 Fe 1− x Cr x MoO 6 ( x =0.00, 0.03, 0.07, 0.1) powder have been prepared by a solid-state reaction method. The crystalline structure of all the Cr-doped samples was tetragonal ( I4/mmm ) at room temperature, but the crystal symmetry changes into cubic ( Fm-3m ) above the Curie temperature. As the Cr-doping range increases, the saturation magnetization decreases and the coercivity force increase. Mossbauer spectra are shown the line broadening and 1, 6 and 3, 4 linewidth difference due to the anisotropic hyperfine field fluctuation.
