We propose a theoretical model with Dzyaloshinskii-Moriya interaction for the polar magnet Fe2Mo3O8. Via Wigner-Jordan transformation, the electric polarization Px and the magnetization M formula are obtained. Combined with the Green's function equation of motion method, we show that the electric polarization can be induced by a magnetic ordering and manipulated by a magnetic field. There exist structural and metamagnetic transitions in the Fe2Mo3O8 system, which is in agreement with the experimental results.
