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…
Universality of magnetic susceptibility in the conical state of kagome ferromagnet FeSn
Lilian Prodan, Donald M. Evans, Lukas Puntigam +2
We report universal behavior of the differential magnetic susceptibility (DMS) in the conical phase that mediates the spin-reorientation (SR) transition of the kagome ferromagnet F…
Contrasting magnetic behavior in MnSc_2X_4 (X = S, Se) spinel compounds investigated by magnetoelastic studies
J. Grumbach, J. Sourd, M. Deeb +12
The spinel compounds MnSc_2X_4 are highly frustrated and candidate materials for vortex-like 3q magnetic states, such as skyrmions, with propagation vectors in the [111] plane. Bec…
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…
Easy-cone state mediating the spin reorientation in topological kagome magnet FeSn
L. Prodan, D. M. Evans, A. S. Sukhanov +7
We investigated temperature-driven spin reorientation (SR) in the itinerant kagome magnet FeSn using high-resolution synchrotron x-ray diffraction, neutron diffraction, mag…
