Magnetic chirality and electric polarization in MnO

Wakimoto, Shuichi ; Kimura, Hiroyuki*; Fukunaga, Mamoru*; Sakamoto, Yuma*; Noda, Yukio*; Kakurai, Kazuhisa

MnO is a multiferroic compound in which ferroelectricity is driven by magnetism. So far two models have been proposed to explain spin-driven ferroelectriciry in this compound, and models. By detailed investigation of magnetic chirality by polarized neutron diffraction, we have succeeded to distinguish these two contributions to the ferroelectric polarization. We conclude that the mechanism is dominant in the commensurate phase and the mechanism is dominant in the low temperature incommensurate phase.
