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…
Low-field magnetization processes of hexagonal easy-plane altermagnet -MnTe
Sahana RöÃler, Victoria Ginga, Marcus Schmidt +5
Single crystals of -MnTe were synthesized by chemical vapor transport using iodine as the transport reagent. Structural characterization by powder x-ray diffraction confirmed t…
Proximate spin-liquid behavior in the double trillium lattice antiferromagnet KCo(SO)
A. Magar, K. Somesh, M. P. Saravanan +6
We report proximate quantum spin liquid behavior in KCo(SO) with the magnetic Co ions embedded on a highly frustrated three-dimensional double trillium latti…
Tunable Dirac nodal line in orthorhombic RuO
Ece Uykur, Oleg Janson, Victoria A. Ginga +3
Pressure evolution of RuO2 is studied using single-crystal x-ray diffraction in a diamond anvil cell, combined with \textit{ab initio} band-structure calculations. The tetragonal r…
