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…
Suppression of magnetism in CoSnS under external pressure
A. Chmeruk, D. Jones, R. Balducci +13
The ability to control the magnetic state provides a powerful means to tune the underlying band topology, enabling transitions between distinct electronic phases and the emergence…
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…
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…
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…
