Magnetic circular dichroism of THz modes and selection rules of Raman-active optical phonons in the polar altermagnet candidate \ce{Mn2Mo3O8}
F. Schilberth, K. Vasin, M. Knauft +14
We investigated the magnetic and vibrational excitations in the collinear altermagnet candidate \ce{Mn2Mo3O8} by temperature dependent Raman scattering and magneto-optical THz time…
Optical phonons as a testing ground for spin group symmetries
F. Schilberth, M. Kondákor, D. Ukolov +12
Lattice vibrations are highly sensitive to crystal symmetries and their changes across phase transitions. The latter can modify irreducible (co)representations and corresponding in…
All-optical control of antiferromagnetic domains via an inverse optical magnetoelectric effect
Shingo Toyoda, Vilmos Kocsis, Yusuke Tokunaga +5
Antiferromagnets are a promising platform for next-generation spintronics due to their ultrafast spin dynamics and robustness to external fields. All-optical control of antiferroma…
Large magnetoreflectance and optical anisotropy due to flat bands in the frustrated kagome magnet HoAgGe
F. Schilberth, L. DeFreitas, K. Zhao +7
We report peculiar optical properties of the frustrated itinerant magnet HoAgGe, which exhibits multiple magnetically ordered states obeying the kagome spin-ice rule. The optical c…
Generation of Weyl points and a nodal line by magnetization reorientation in CoSnS
F. Schilberth, M. -C. Jiang, F. Le Mardelé +11
Topological magnets exhibit fascinating properties like topologically protected surface states or anomalous transport phenomena. While these properties can be significantly altered…
