Spherical neutron polarimetry study of hysteresis in multiferroic MnWO4

Abstract

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