Abstract

We have recently demonstrated that multiferroics host exotic optical phenomena, such as non-reciprocal directional dichroism [1] and natural optical activity [2], for spin-wave excitations owing to the strong dynamic magnetoelectric coupling. The observed large optical anisotropies can pave the way for novel THz applications e.g. unidirectional waveguides or polarization rotators.
