Nearly-Resonant Crystalline-Phononic Coupling in Quantum Spin Liquid Candidate CsYbSe
Yun-Yi Pai, Claire E. Marvinney, Liangbo Liang +10
CsYbSe, a recently identified quantum spin liquid (QSL) candidate, exhibits strong crystal electric field (CEF) excitations. Here, we identify phonon and CEF modes with Raman s…
Spin and Orbital Effects on Asymmetric Exchange Interaction in Polar Magnets: M(IO3)2 (M = Cu, Mn)
Ebube E. Oyeka, Michal J. Winiarski, Maurice Sorolla +3
We study how spin and orbital effects influence the capability of promoting Dzyaloshinskii-Moriya (DM) interaction by studying the two magnetic polar materials, Cu(IO3)2 (S = 1/2 w…
Witnessing quantum criticality and entanglement in the triangular antiferromagnet KYbSe
A. O. Scheie, E. A. Ghioldi, J. Xing +20
The Heisenberg triangular lattice quantum spin liquid and the phase transitions to nearby magnetic orders have received much theoretical attention, but clear experimental manifesta…
Potential Skyrmion Host Fe(IO3)3: Connecting Stereo-active Lone-Pair Electron Effects to the Dzyaloshinskii-Moriya Interaction
Ebube E. Oyeka, Michal J. Winiarski, Artur Blachowski +3
Magnetic skyrmions, which are topologically distinct magnetic spin textures, are gaining increased attention for their unique physical properties and potential applications in spin…
Quantifying uncertainties in crystal electric field Hamiltonian fits to neutron data
Allen Scheie
We systematically examine uncertainties from fitting rare earth single-ion crystal electric field (CEF) Hamiltonians to inelastic neutron scattering data. Using pyrochlore and dela…
Dirac magnons, nodal lines, and nodal plane in elemental gadolinium
Allen Scheie, Pontus Laurell, Paul A. McClarty +4
We investigate the magnetic excitations of elemental gadolinium (Gd) using inelastic neutron scattering, showing that Gd is a Dirac magnon material with nodal lines at and noda…
Spin exchange Hamiltonian and topological degeneracies in elemental gadolinium
Allen Scheie, Pontus Laurell, Paul A. McClarty +4
We present a comprehensive study of the magnetic exchange Hamiltonian of elemental Gadolinium. We use neutron scattering to measure the magnon spectrum over the entire Brillouin zo…
Hidden low-temperature magnetic order revealed through magnetotransport in monolayer CrSBr
Evan J. Telford, Avalon H. Dismukes, Raymond L. Dudley +13
Magnetic semiconductors are a powerful platform for understanding, utilizing and tuning the interplay between magnetic order and electronic transport. Compared to bulk crystals, tw…
Beyond magnons in Nd2ScNbO7: An Ising pyrochlore antiferromagnet with all in all out order and random fields
A. Scheie, M. Sanders, Yiming Qiu +3
We report the low temperature magnetic properties of Nd pyrochlore . Susceptibility and magnetization show an easy-axis moment, and heat capacity reveals a…
Witnessing entanglement in quantum magnets using neutron scattering
A. Scheie, Pontus Laurell, A. M. Samarakoon +6
We demonstrate how quantum entanglement can be directly witnessed in the quasi-1D Heisenberg antiferromagnet KCuF. We apply three entanglement witnesses --- one-tangle, two-tan…
