“…The termg 2 @M 2 =@z is important only for domain walls that appear near the point of the phase transition [33,35] (Table 1, types III-IV). The magnetic point group of the domain wall is derived from the crystal symmetry and cannot exceed it [36]. The magnetic point group of the domain wall is determined by the domain wall plane orientation and crystal sample orientation.…”

a b s t r a c tIt was shown that free energy density of the local flexomagnetoelectric effect is determined by the four phenomenological constants in case of the cubic (hexoctahedral) crystal. The well-known singleconstant Lifshitz invariant term is correct only when fixed electric polarization induces the inhomogeneity of the magnetization. Proposed phenomenological theory was applied to the magnetic domain walls. The domain wall structure has been investigated in details. The four-constant phenomenological theory conforms to the symmetry based predictions (Bar'yakhtar et al., 1984, [12]). The proposed experimental verification of the four-constant flexomagnetoelectric phenomenology is a detection of the shift of the Né el domain walls under the strong homogeneous electric field.

Abstract.A local flexomagnetoelectric ) effect in the magnetic domain walls (DWs) of the cubic hexoctahedral crystal has been investigated on the basis of a symmetry analysis.The strong connection between magnetic symmetry of the DW and the type of the distribution of the electric polarization was shown. Results were systemized in the scope of the DW chirality. It was shown, that new type of the local flexomagnetoelectric coupling can be experimentally detected using the external homogeneous electric field.
