Description
I will present our current understanding of the magnetic degrees of freedom in Ni3TeO6, a non-centrosymmetric hexagonal material that undergoes a field-induced first-order phase transition with emergent multiferroic properties. Using neutron scattering under in-plane magnetic fields we find that the collinear spin structure becomes likely chiral at large fields. The low-energy spin-wave excitations at zero field act as a precursor of the putative chiral state. They split in field and provide evidence for a Zeeman-induced mode condensation at the magnetic phase boundary.
