Inhomogeneous dynamic state in the double trillium lattice antiferromagnet KBaFe(PO)
S. J. Sebastian, S. S. Islam, R. Kolay +11
The three-dimensional (3D) magnet KBaFe(PO) hosts a double-trillium lattice of Fe (spin, ) ions offering a prototypical platform to study the frustration…
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…
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…
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…
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…
Fermi-liquid behavior of non-altermagnetic RuO
Maxim Wenzel, Ece Uykur, Sahana RöÃler +5
Presence of magnetism in potentially altermagnetic RuO has been a subject of intense debate. Using broadband infrared spectroscopy combined with density-functional band-structu…
