Spectroscopic signatures of magnetization-induced band renormalization and strong spin-charge-lattice coupling in EuZn${}_2$As${}_2$

Zhiyu Liao, Boxuan Li, Shaohui Yi +9

We report an infrared spectroscopy study of the antiferromagnetic (AFM) insulator EuZn${}_2$As${}_2$ over a broad frequency range, spanning temperatures both above and below the AFM tr…
