Enhanced gyrotropic birefringence and natural optical activity on electromagnon resonance in a helimagnet

Gyrotropic birefringence is expected to emerge from the magnetoelectric coupling. Here, the authors find polarity and chirality arising from the helical spin order exhibit enhanced optical activities, gyrotropic birefringence and natural optical activity, on the electromagnon resonance.
