Magnetic and dielectric properties of Eu1-xYxMnO 3 (0 ≥ x ≥ 0.4) were studied in pulsed-magnetic fields up to 55 T. In paraelectric EuMnO3, application of magnetic fields along the b-axis causes a first order transition to the ferroelectric phase with the electric polarization parallel to the a-axis. Similar first order transitions are also observed in Eu0.6Y0.4MnO3, in which the ferroelectric phase is already stable in zero field. A possible microscopic origin of the novel multiferroic phase in high field is discussed.
