    Abstract

    The charge ordering and the magnetic ordering in InFe2O 4 were investigated using samples free of impurity Fe 3O4. X-ray diffraction, magnetic susceptibility, magnetization, Mössbauer spectroscopy, and dielectric constant measurements consistently showed that both these orderings occurred between 230 and 250 K. This temperature range is much smaller than the corresponding one in the cooling of electronic ferroelectric LuFe2O4, where charge ordering occurs at 320 K and magnetic ordering occurs at 250 K.
