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…

Large magnon dichroism and other optical properties of hexagonal ferrite h-Lu0.6Sc0.4FeO3 with altermagnetic A2 spin ordering
V. A. Martinez, A. A. Sirenko, L. Bugnon +8
Multiferroic hexagonal h-Lu0.6Sc0.4FeO3 single crystals with non-collinear spins were studied using the THz and Raman scattering spectroscopies and ellipsometry. Antiferromagnetic…
