| 中文摘要 | The structural and physical properties of the recently discovered electronic ferroelectric materials LuFe2O4 and Lu2Fe3O7 have been investigated for Mg substitution of Fe. X-ray diffraction data demonstrate that the lattice parameters in both systems change progressively with increasing Mg content, with a smaller unit cell volume on replacing Fe2+ by Mg2+. X-ray absorption near-edge spectroscopy experiments at the Fe K-edge show that the average Fe oxidation state is slightly increased along with Mg doping in Lu2Fe3O7 materials, consistent with isomorphous replacement of Fe2+ by Mg2+. Measurements of dielectric properties demonstrate that Mg doping could have an effect on the electron hopping energy between Fe2+ and Fe3+ ions. Transmission electron microscopy and magnetization analysis reveal that Mg doping in LuFe2O4 has a much greater influence than in Lu2Fe3O7 on both the charge ordering and the low-temperature magnetic properties. |
