Abstract

Electric control of spin chirality in a magnetically frustrated multiferroic is demonstrated through polarized magnetic neutron diffraction. Cooling to the cycloidal multiferroic phase of Ni ^ d3 ^ V ^ d2 ^ O ^ d8 ^ in an electric field causes the incommensurate Bragg reflections to become neutron spin polarizing, the sense of neutron polarization reversing with E. Quantitative analysis indicates the E-treated sample is chiral, the chirality controlled by E. We further show close association between chiral and ferro-electric domains through E-driven spin chiral and electric polarization hysteresis. We suggest that the denite spin chirality is achieved through magneto-elastically induced Dzyaloshinskii-Moriya interactions.
