Abstract
AbstractCross correlation between magnetism and electricity in a solid can host magnetoelectric effects, such as magnetic (electric) induction of polarization (magnetization). A key to attain the gigantic magnetoelectric response is to find the efficient magnetism–electricity coupling mechanisms. Among those, recently the emergence of spontaneous (ferroelectric) polarization in the insulating helimagnet or spiral‐spin structure was unraveled, as mediated by the spin‐exchange and spin–orbit interactions. The sign of the polarization depends on the helicity (spin rotation sense), while the polarization direction itself depends on further details of the mechanism and the underlying lattice symmetry. Here, we describe some prototypical examples of the spiral‐spin multiferroics, which enable some unconventional magnetoelectric control such as the magnetic‐field‐induced change of the polarization direction and magnitude as well as the electric‐field‐induced change of the spin helicity and magnetic domain.

- In general magnetically‐induced domains can be mutually converted by the symmetry operations that are broken by magnetic order. This analysis allows six possible multiferroic domains with different polarization directions for CuFe1−xGaxO2. For details see [61].

- Note that the symmetry‐based analysis described here only considers the local site symmetry on the magnetic ion. While this gives the necessary condition for the emergence of ferroelectricity the existence of more global symmetry (such as an inversion center between two magnetic layers or a glide plane) may often prevent the system from being polar.
