摘要：

Spontaneous electric polarization of magnetite has been studied by measuring the polarization reversal charge along the a axis. The magnitude of the polarization at 4.2 K is estimated to be over 52 muC cm-2. This is about ten times larger than the magnitude reported so far and comparable order to that of BaTiO3.
