Description
The interplay among electronic charge, orbital, spin and lattice degrees of freedom in quantum materials can stabilize a variety of collective phenomena. Substantial understanding concerning the microscopic origin of these correlated quantum phases is gained through microscopic studies susceptible to the various degrees of freedom, and their dependencies on external tuning parameters. Here, we will show how the combination of various neutron spectrometers equipped with different sample environments allowed us to clarify the mechanism behind the multiferroic properties of Ni3TeO6. Our studies show that its non-chiral crystal structure gives raise to non-reciprocal chiral low-energy magnons, whose condensation trigger a direct coupling between the material’s electric polarization and magnetic properties.
