Magnetic rare earths R have been proven to have a significant effect on the multiferroic properties of the orthorhombic manganites R MnO 3 . A re-examination of previous results from synchrotron based x-ray scattering experiments suggests that symmetric exchange striction between neighboring R and Mn ions may account for the enhancement of the ferroelectric polarization in DyMnO 3 as well as the magnetic-field induced ferroelectricity in GdMnO 3 . In general, adding a second magnetic species to a multiferroic material may be a route to enhance its ferroelectric properties.
