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…
Magneto-optical signatures of plateau states in the kagome spin-ice HoAgGe
F. Schilberth, L. DeFreitas, K. Zhao +11
Coupling of itinerant electrons to non-collinear spin structures in frustrated rare-earth magnets leads to unusual transport properties. While these complex magnetic orders are exp…
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…
Optical anisotropy of the kagome magnet FeSn: Dominant role of excitations between kagome and Sn layers
J. Ebad-Allah, M. -C. Jiang, R. Borkenhagen +8
Antiferromagnetic FeSn is considered to be a close realization of the ideal two-dimensional (2D) kagome lattice, hosting Dirac cones, van Hove singularities, and flat bands, as it…
Giant natural optical rotation from chiral electromagnons in a collinear antiferromagnet
D. Maluski, M. Langenbach, D. Szaller +8
In NiTeO with a chiral crystal structure, we report on a giant natural optical rotation of the lowest-energy magnon. This polarization rotation, as large as 140 deg/mm, cor…
Magnetic resonances of multiferroic TbFe(BO)
Dávid Szaller, Vilmos Kocsis, Sándor Bordács +6
Low-energy magnetic excitations of the easy-axis antiferromagnet TbFe(BO) are investigated by far-infrared absorption and reflection spectroscopy in high magnetic field…
