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-…

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…

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…

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…

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…
