The interrelation between spatial modulation of order parameter and electric polarization, known as flexoelectric effect in liquid crystals in the case of magnetic media appears in inhomogeneous spin distribution and causes various effects: - Spatially modulated spin structures stabilized by electric polarization in multiferroics and chiral domain structure in magnetic films with broken central symmetry - Ferroelectric polarization induced by magnetic ordering in multiferroics, and electric polarization associated with magnetic domain walls - The pinning of antiferromagnetic domain structure at ferroelectric domain walls as well as spin modulation induced by ferroelectric domain walls.
