Ferroelectricity Driven by the Noncentrosymmetric Magnetic Ordering <?format ?>in Multiferroic : A First-Principles Study
The ground state structural, electronic, and magnetic properties of multiferroic TbMn 2 O 5
are investigated via first-principles calculations. We show that the ferroelectricity in TbMn 2 O
5 is driven by the noncentrosymmetric magnetic ordering, without invoking the spin-orbit
coupling and noncollinear spins. The intrinsic electric polarization in this compound is
calculated to be 1187 nC cm-2, an order of magnitude larger than previously thought.
