Abstract

Spiral multiferroics whose ferroelectricity is driven by spatial spin modulation attract considerable attention due to strong magnetoelectric coupling observed in them. The present paper shows that a similar mechanism is involved in the case of conventional micromagnetic structures such as domain walls. It is shown experimentally and theoretically that the domain wall in iron garnet films has electric polarization which can be switched by an external magnetic field. From the practical application standpoint it provides an intriguing opportunity of micromagnetic structures controlled by an electric field in low-power-consumption spintronic and magnonic devices.
