Abstract: Various phenomena related to inhomogeneous magnetoelectric interaction areconsidered. The interrelation between spatial modulation of order parameter andelectric polarization, known as flexoelectric effect in liquid crystals, in thecase of magnetic media appears in a form of electric polarization induced byspin modulation and vice versa. This flexomagnetoelectric interaction is alsorelated to the influence of ferroelectric domain structure on antiferromagneticvector distribution, and to the magnetoelectric properties of micromagneticstructures. The influence of inhomogeneous magnetoelectric interaction ondynamic properties of multiferroics, particularly magnon spectra is alsoconsidered.
