Measurements of magnetization and electric polarization performed for the TbMnO3 film grown onto the single crystal [100] SrTiO3 substrate using magnetron sputtering technique exhibit series of anomalies related to the magnetic and electric ordering of the Tb3+ and Mn3+ sublattices. The detailed temperature dependences of the electric polarization and dielectric constant of the TbMnO3 film have shown that the ferroelectric phase appears below 30 K in magnetic field H > 1 T applied in-plane and out-of-plane of the film.
