Broad-band ellipsometry study of the anisotropic dielectric response of YAlO3
Laurent Bugnon, Christian Bernhard, Premysl Marsik
We present a broad band (THz to UV) ellipsometry study of the anisotropic dielectric response of the orthorhombic perovskite YAlO3. The ellipsometric measurements have been perform…

Spectroscopic signatures of magnetization-induced band renormalization and strong spin-charge-lattice coupling in EuZnAs
Zhiyu Liao, Boxuan Li, Shaohui Yi +9
We report an infrared spectroscopy study of the antiferromagnetic (AFM) insulator EuZnAs over a broad frequency range, spanning temperatures both above and below the AFM tr…
