Tunable inter-bilayer magnetic correlations and candidate multipolar physics in the van der Waals oxyhalides DyOCl, DyOBr, and DyOI
F. C. Brooks, X. Bai, J. Bacsa +5
Rare-earth van der Waals magnets provide a route to combining strong spin-orbit coupling, large magnetic moments, and reduced dimensionality in bulk crystals. We report a comparati…
Revealing Intrinsic Anisotropy of Collective Magnetic Excitations in Twinned Crystals of a Kitaev-Heisenberg Quantum Magnet
Naipeng Zhang, Nikolai Simonov, Mykhaylo Ozerov +11
Quantum magnets with competing interactions often emerge from delicate balances among microscopic parameters, making it essential to disentangle intrinsic spin dynamics from extrin…
Field-induced quasi-bound state within the two-magnon continuum of a square-lattice Heisenberg antiferromagnet
F. Elson, M. Nayak, A. A. Eberharter +14
Quantum magnets in two dimensions display strong quantum interaction effects even when magnetically ordered. Using the metal-organic framework material CuF(DO)(pyz), we…
Spin dynamics of the spin-1 triangular lattice Heisenberg antiferromagnet KNi(SeO)
Chaebin Kim, Sathvik Nallapati, E. A. Ghioldi +6
Strong quantum fluctuations and unconventional spin dynamics are well established in the spin-1/2 triangular lattice Heisenberg antiferromagnet. However, their survival in the spin…
Semiclassical Routes to the -RuCl Scattering Continuum via Model MetaAnalysis
Chaebin Kim, Martin Mourigal
-RuCl is a leading material for proximate Kitaev magnetism. We address the origin of the broad, -point centered excitation continuum observed by inelastic neutron scatt…
Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state
Chaebin Kim, Sumedh Rathi, Naipeng Zhang +15
Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electri…
