From Narrow-gap Semiconductor to Metallic Altermagnet: Optical Fingerprints of Co-Doped FeSb2
R. Mathew Roy, M. Povolotskiy, J. Kirschke +11
The realization of bulk metallic altermagnetism has remained elusive despite the growing number of candidate materials. Here, we present evidence that moderate cobalt substitution…

Fermi-liquid behavior of non-altermagnetic RuO
Maxim Wenzel, Ece Uykur, Sahana Rößler +5
Presence of magnetism in potentially altermagnetic RuO has been a subject of intense debate. Using broadband infrared spectroscopy combined with density-functional band-structu…

Phonon and magnon dynamics across antiferromagnetic transition in 2D layered van der Waals material CrSBr
E. Uykur, A. A. Tsirlin, F. Long +6
We report temperature-dependent reflectivity spectra of the layered van der Waals magnet CrSBr in the far-infrared region. Polarization-dependent measurements resolve the vibration…
