A complex permittivity at a low level of excitation signal was measured in ceramic LuFe2O4. A Debye-type relaxation response with a strong temperature dependence of a characteristic frequency was observed in accordance with earlier works. A small DC bias of about 10 V/cm led to unusual changes in th...
