Ferroelectricity driven by the non-centrosymmetric magnetic ordering in multiferroic TbMn_2O_5: a first-principles study

Abstract

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 non-centrosymmetric magnetic ordering, without invoking the spin-orbit coupling and non-collinear spins. The {\it intrinsic} electric polarization in this compound is calculated to be 1187 $nC\cdot$ cm${}^{-2}$, an order of magnitude larger than previously thought.
