Abstract

• Charge order is proposed as a driving force behind ferroelectricity in iron fluoride K FeII FeIII F . By 0:6 0:6 0:4 3 means of density functional theory, we propose several noncentrosymmetric d5=d6 charge-ordering patterns, each giving rise to polarization with different direction and magnitude. Accordingly, we introduce the concept of ''ferroelectric anisotropy'' (peculiar to improper ferroelectrics with polarization induced by electronic degrees of freedom), denoting the small energy difference between competing charge-ordered states. Moreover, we suggest a novel type of charge-order-induced ferroelasticity: a monoclinic distortion is induced by a specific charge-ordering pattern, which, in turn, determines the direction of polarization. K FeII FeIII F therefore emerges as a prototypical compound, in which the 0:6 0:6 0:4 3 intimately coupled electronic and structural degrees of freedom result in a peculiar multiferroicity.
