- W2920676280 abstract "We report a ferroelectric order at $ensuremath{sim}98$ K for ${mathrm{NiFe}}_{2}{mathrm{O}}_{4}$, which carries an inverse spinel structure with a centrosymmetric $Fdoverline{3}m$ structure at room temperature. The value of spontaneous electric polarization is considerably high as $ensuremath{sim}0.29 ensuremath{mu}mathrm{C}/{mathrm{cm}}^{2}$ for 5 kV/cm poling field. The electric polarization decreases considerably ($ensuremath{sim}17%$) around the liquid-nitrogen temperature upon application of 50 kOe field, proposing a significant magnetoelectric coupling. The synchrotron diffraction studies confirm a structural transition at $ensuremath{sim}98$ K to a noncentrosymmetric structure of $P{4}_{1}22$ space group. The occurrence of polar order is associated with an ordered occupancy of Ni and Fe atoms at the octahedral sites of the $P{4}_{1}22$ structure, instead of random occupancies at the octahedral site of the inverse spinel structure. The results propose that ${mathrm{NiFe}}_{2}{mathrm{O}}_{4}$ is a member in the type-II multiferroics." @default.
