Abstract

We report low frequency dielectric dispersions of ErFe₂O₄ in which equal numbers of Fe²⁺ and Fe³⁺ ions occupy the sites on a triangular lattice. The first dispersion observed between 200 K and 300 K is explained qualitatively on a model that spontaneous polarization is present in the crystal below the Verwey transition. The second dispersion at higher temperatures is characterized by a few glass-like features. It was interpreted by successive freezing of the local dipole moments accompanied by short-range ordering of Fe²⁺ and Fe³⁺ ions.
