N2 - We report the magnetic field effect on the dielectric constant of the charge-ordered ferroelectric LuFe2O4. Below the Néel temperature of 240 K, we found decreases in capacitance and resistance by the magnetic field. The variation in dielectric constant with the magnetic field was investigated by inverse complex capacitance analysis with a series of equivalent electric circuits having a log-normal distribution of the relaxation time. The phenomenon can be explained by the spin- and charge-ordered domain model, in which the entropy of Fe spins affects the arrangement of Fe charges.
