Magnetically-Driven Ferroelectric Atomic Displacements in perovskite like YMnO3

Abstract

Magnetically-driven ferroelectric atomic displacements of the order of 10${}^{-3}Angstromhavebeenobservedinorthorhombic(perovskitelike)YMnO$_3$byasingle-crystalsynchrotronx-raydiffraction.TherefinedpolarstructureshowsthecharacteristicbondalternationdrivenbytheexchangestrictioninstaggeredMn-O-Mnarrayswith$\uparrow\uparrow\downarrow\downarrow$ type ordering, giving rise to a spontaneous polarization along a-axis. First-principles calculations based on the Berry phase method as well as on the experimentally refined crystal structure can reproduce the observed polarization value.
