Coupling of magnetic and lattice collective excitations in the 2D van der Waals antiferromagnet FePS${}_3$

Kartik Panda, Itzik Kapon, Dumitru Dumcenco +3

We combine polarized infrared magneto-transmission and Faraday angle rotation measurements to map the collective excitations of the van der Waals antiferromagnet FePS${}_3$. Below th…
