Anisotropy, frustration and saddle point in the twisted Kagome antiferromagnet ErPdPb
Resham Babu Regmi, Sk Jamaluddin, Y. Lee +14
The kagome lattice, with its inherent geometric frustration, provides a rich platform for exploring intriguing magnetic phenomena and topological electronic structures. In reduced-…
Accurate calculation of light rare-earth magnetic anisotropy with density functional theory
Liqin Ke, R. Flint, Y. Lee
Density functional theory (DFT) has long struggled to treat light rare-earth magnetism. We show that this difficulty arises from an overestimate of the charge asphericity, and…
Doping-induced Spin Reorientation in Kagome Magnet TmMn6Sn6
Mohamed El Gazzah, Po-Hao Chang, Y. Lee +7
The kagome-lattice compounds RMn6Sn6 (R is a rare earth element), where the Mn atoms form a kagome net in the basal plane, are currently attracting a great deal of attention as the…
Nature of quantum criticality in the Ising ferromagnet TbVSn
Tianxiong Han, R. D. McKenzie, Joanna Blawat +10
TbVSn is a topological metal where ferromagnetic Tb ions with strong uniaxial magnetic anisotropy interact with V kagome layers. Inelastic neutron scattering (INS) measurem…
Three-dimensional nature of anomalous Hall conductivity in YMn6Sn6-xGax, x ~ 0.55
Hari Bhandari, Zhenhua Ning, Po-Hao Chang +8
The unique connectivity of kagome lattices gives rise to topological properties, such as flat bands and Dirac cones. When combined with ferromagnetism and a chemical potential near…
Spin dynamics in itinerant antiferromagnet SrCrAs
Zhenhua Ning, Pinaki Das, Y. Lee +6
SrCrAs is an itinerant antiferromagnet in the same structural family as the SrFeAs high-temperature superconductors. We report our calculations of exchange-coupling…
Toward a first-principles theory of rare-earth ions in crystals
Y. Lee, Z. Ning, R. Flint +3
Density functional theory (DFT), including its extensions designed to treat strongly correlated localized electron systems such as DFT+ and DFT+dynamical mean field theory, has…
Coexistence of Ferromagnetism and Antiferromagnetic Dimers in Topological Insulators
Farhan Islam, Deborah Schlagel, Yongbin Lee +6
The addition of magnetic impurities in topological insulators can drive ferromagnetic order that leads to novel quantum anomalous Hall transport well below the Curie temperature. T…
Magnetic interactions and excitations in SrMnSb
Zhenhua Ning, Bing Li, Weilun Tang +7
The magnetic interactions in the antiferromagnetic (AFM) Dirac semimetal candidate SrMnSb are investigated using \textit{ab initio} linear response theory and inelastic neutron…
Chiral and flat-band magnetic cluster excitations in a ferromagnetic kagome metal
S. X. M. Riberolles, Tyler J. Slade, Tianxiong Han +7
TbMn6Sn6 is a metallic ferrimagnet that displays signatures of band topology arising from a combination of uniaxial ferromagnetism and spin-orbit coupling within its Mn kagome laye…
