Chiral magnetic excitations in the RMn6Sn6 kagome metals (R=Tb, Ho, Er, and Y)
Christopher J. Ranlett, Tianxiong Han, S. X. M. Riberolles +9
Recent inelastic neutron scattering (INS) investigations of the kagome metal TbMn6Sn6 reveal novel chiral magnetic excitations associated with the kagome layer. These excitations a…
Crystal electric field excitations and an effective-spin- ground doublet in the hyperkagome magnet YbScGaO
Tingjun Zhang, Zehao Wang, Douglas L. Abernathy +4
We use inelastic neutron scattering (INS) to determine the crystal electric field (CEF) excitations of Yb in the rare-earth hyperkagome magnet YbScGaO. Th…
Nature of magnetism in bilayer nickelate La3Ni2O7 single crystals
Lixing Chen, Enkang Zhang, Yiqing Hao +10
The recent discovery of high-temperature superconductivity in pressurized and thin film nickelates has generated intense interest, yet the nature of magnetism in their ambient-pres…
Anisotropic magnons in a layered honeycomb ferromagnet
Travis J. Williams, Douglas L. Abernathy, Mark D. Lumsden +2
Recent experimental and theoretical studies have suggested a possible Dirac magnon gap in the two-dimensional ferromagnetic semiconductor CrSiTe. Detailed neutron scattering me…
Anomalous Electrical Transport in the Kagome Magnet YbFeGe
Weiliang Yao, Supeng Liu, Hodaka Kikuchi +19
Two-dimensional (2D) kagome metals offer a unique platform for exploring electron correlation phenomena derived from quantum many-body effects. Here, we report a combined study of…
Crystal field splittings and magnetic ground state of the square-lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 with Jeff = 1/2
Pyeongjae Park, Qianli Ma, G. Sala +5
We report on the crystal field level splitting and magnetic ground state of the Jeff = 1/2 square lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 using powder inelastic neutron sca…
Spin Dynamics of the Centrosymmetric Skyrmion Material GdRu2Si2
Joseph A. M. Paddison, Juba Bouaziz, Andrew F. May +6
Magnetic skyrmion crystals are traditionally associated with non-centrosymmetric crystal structures; however, it has been demonstrated that skyrmion crystals can be stabilized by c…
Muon spin relaxation and inelastic neutron scattering investigations of all-in/all-out antiferromagnet Nd2Hf2O7
V. K. Anand, D. L. Abernathy, D. T. Adroja +3
Nd2Hf2O7, belonging to the family of geometrically frustrated cubic rare earth pyrochlore oxides, was recently identified to order antiferromagnetically below T_N = 0.55 K with an…
Pseudo-Goldstone magnons in the frustrated S=3/2 Heisenberg helimagnet ZnCr2Se4 with a pyrochlore magnetic sublattice
Y. V. Tymoshenko, Y. A. Onykiienko, T. Mueller +13
Low-energy spin excitations in any long-range ordered magnetic system in the absence of magnetocrystalline anisotropy are gapless Goldstone modes emanating from the ordering wave v…
Robust antiferromagnetic spin waves across the metal-insulator transition in hole-doped BaMnAs
M. Ramazanoglu, A. Sapkota, Abhishek Pandey +8
BaMnAs is an antiferromagnetic insulator where a metal-insulator transition occurs with hole doping via the substitution of Ba with K. The metal-insulator transition ca…
