抜粋

We studied the multiferroic properties of the incommensurate spiral phase of Mn_1-x Co_x WO₄ using single-crystal neutron-diffraction and ferroelectric measurements. Whereas the rotational plane of the spin spiral is parallel to the b axis for x≤0.05, it flops by 90°for x=0.10. As a result, the direction of the ferroelectric polarization also flops from the b to the a axis. These results show that the orientation of the ferroelectric polarization in MnWO₄ can be controlled via chemical doping.
