摘要：

The electric-field dependence of the magnetic structure of multiferroic MnWO4 has been directly investigated using spherical neutron polarimetry as a function of temperature. The application of an electric field is shown to drive the magnetic structure to a single 'chiral' domain. The magnitude of the electric field required to do this is shown to increase upon cooling. The coupling between the magnetic order and electric polarization is further demonstrated.
