The existence of ferroelectricity in magnetite has been established by determining the c -axis component spontaneous polarization at 4.2 K. ferroelectric D - E hysteresis loop was observed changing applied electric field stepwise 5 kV/cm intervals 10 s between -15 and 15 kV/cm. It found that, K, coercive is extremely high leakage current still prominent. switching process d 20
