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…
Magnetic and electric properties of the metallic kagome antiferromagnet CrRhAs
Franziska Breitner, Bin Shen, Anton Jesche +2
CrRhAs is an antiferromagnetic kagome metal predicted to host a nontrivial spin texture with vector spin chirality [Huang \textit{et al.}, \textit{npj Quantum Mater.} \textbf{8}, 3…
Thermodynamic signatures of a field-induced ordered intermediate phase in NaCoTeO
Prashanta K. Mukharjee, Sebastian Erdmann, R. Kalaivanan +4
The honeycomb cobaltate NaCoTeO has recently been proposed as a candidate material for hosting field-induced quantum spin liquid (QSL) behavior. Here, we present a comp…
Quantum spin ladder with ferromagnetic rungs in BiCuO(SO)
Rodolfo A. Rangel Hernandez, Kirill Yu. Povarov, Sergei Zvyagin +3
We introduce BiCuO(SO) as a rare example of a spin-ladder magnet with ferromagnetic interactions on the rungs. Its magnetic response is studied through measurements of…
Revisiting the symmetry and optical phonons of altermagnetic -MnTe
Ece Uykur, Marcos V. Gonçalves-Faria, Sahana RöÃler +5
Using infrared (IR) and Raman spectroscopies combined with high-resolution x-ray diffraction, we address several controversial aspects of altermagnetic -MnTe. We show that mech…
Beyond kagome: -bands in kagome metals
Alexander A. Tsirlin, Ece Uykur
We review recent studies on quantum materials where transition-metal atoms give rise to -bands typical of kagome metals. Using examples from several material families - AVSb…
