We have measured temperature dependence of magnetic and dielectric properties in high quality stoichiometric single-crystals of magnetite (Fe_3O_4). At low temperatures, below the Verwey transition, both ac susceptibility and ac permittivity reveal similar relaxation processes. We discuss these effects in connection with domain structure and variable range hopping mechanism of electrical conductivity.
