Control of the polarization flop direction in multiferroic RMnO3 (R = Tb, Dy) by a tilted magnetic field
In spin-driven ferroelectrics, the electric polarization is often modified by the application of a magnetic field. RMnO3 (R = Tb, Dy) is a well known multiferroic with electric polarization along the c-axis induced by the cycloidal ordering of Mn spin moments in the bc plane, which can be explained by the inverse effect of Dzyaloshinski-Moriya interaction. RMnO3 exhibits an electric-polarizatio...
متن کاملRare earth magnetism and ferroelectricity in RMnO3
Magnetic rare earths R have been proven to have a significant effect on the multiferroic properties of the orthorhombic manganites RMnO3. 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 DyMnO3 as well as the ma...
متن کاملInternal magnetic field effect onmagnetoelectricity in orthorhombicRMnO3 crystals
We have investigated the role of the 4f moment on the magnetoelectric (ME) effect of orthorhombic RMnO3 (R=rare earth ions). In order to clarify the role of the 4f moment, we prepared three samples: (Eu,Y)MnO3 without the 4f moment, TbMnO3 with the anisotropic 4f moment, and (Gd,Y)MnO3 with the isotropic 4f moment. The ferroelectric behaviors of these samples are different from each other in a ...
متن کاملDynamical magnetoelectric effects induced by the Dzyaloshinskii- Moriya interaction in multiferroics
We study the dynamical interplay between ferroelectricity and magnetism in a multiferroic with a helical magnetic order. We show that the dynamical exchange-striction induces a biquadratic interaction between the spins and transverse phonons resulting in quantum fluctuations of the spontaneous ferroelectric polarization P in the ferroelectric phase. The hybridization between the spin wave and t...
متن کاملExperimental observation of ferrielectricity in multiferroic DyMn2O5
One of the major breakthroughs associated with multiferroicity in recent years is the discovery of ferroelectricity generated by specific magnetic structures in some magnetic insulating oxides such as rare-earth manganites RMnO3 and RMn2O5. An unresolved issue is the small electric polarization. Relatively large electric polarization and strong magnetoelectric coupling have been found in those ...
