  A common scenario of magnetoelectric coupling in multiferroics is the
electric polarization induced by spatially modulated spin structures. It is
shown in this paper that the same mechanism works in magnetic dielectrics with
inhomogeneous magnetization distribution: the domain walls and magnetic
vortexes can be the sources of electric polarization. The electric field driven
magnetic domain wall motion is observed in iron garnet films. The electric
field induced nucleation of vortex state of magnetic nanodots is theoretically
predicted and numerically simulated. From the practical point of view the
electric field control of micromagnetic structures is promising for
applications in low-power-consumption spintronic and magnonic devices.
