Abstract
A layer-structure oxide LuFe2O4 shows dielectric dispersions in two te mperature legions below and above the transition between two- and thre e-dimensional charge orderings proposed by a diffraction study. The or igin of the dispersions are considered to be related with electron hop ping between Fe2+ and Fe3+ ions ordered or disordered on triangular la ttices characteristic of this oxide.
