摘要

The Cr doped ordered perovskite powder of Sr2Fe0.93Cr0.07MoO6 has been prepared by a solid-state reaction method. The chemical composition and the crystalline structure of the sample were confirmed with the Rutherford backscattering spectrometer spectrum and X-ray diffraction pattern analysis. The crystalline structure was determined to be tetragonal with lattice parameters a(0) = 5.572 Angstrom and c(0) = 7.900 Angstrom, respectively. The magnetic properties of the Sr2Fe0.93Cr0.07MoO6 have been studied by the vibrating sample magnetometer and the Mossbauer spectroscopy. The saturation magnetization and the coercive force were 26.5 emu/g and 101.2 Oe at room temperature. Mossbauer spectra measurements of the Sr2Fe0.93Cr0.07MoO6 have been taken at various temperatures ranging from 15 to 450 K. Analysis of Mossbauer spectra has considered with next nearest-neighbour interactions and the anisotropic hyperfine field fluctuation. The anisotropic field fluctuation of +H (P+ = 0.85) is greater than that of -H (P_ = 0.15). (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
