Multiferroicity around Verwey transition in Fe3O4 thin films

We report observation of finite remanent polarization (∼10-80 nC/cm2) and reasonably strong magnetoelectric coupling in thin film of Fe3O4 within a temperature range from ∼40 K to Verwey transition temperature TCO ∼120 K. Both the intrinsic capacitance and remanent ferroelectric polarization decreas...
