Emergence of high-mobility carriers in topological kagome bad metal MnSn by intense photoexcitation

Takuya Matsuda, Tomoya Higo, Kenta Kuroda +13

Kagome-lattice materials offer novel playgrounds of exploring topologically nontrivial states of electrons under influence of many-body interactions. A noncollinear kagome antiferr…

Bond Ordering and Molecular Spin-Orbital Fluctuations in the Cluster Mott Insulator GaTaSe

Tsung-Han Yang, S. Kawamoto, Tomoya Higo +8

For materials where spin-orbit coupling is competitive with electronic correlations, the spatially anisotropic spin-orbital wavefunctions can stabilize degenerate states that lead…

Impact of the lattice on magnetic properties and possible spin nematicity in the S=1 triangular antiferromagnet NiGaS

Michael E. Valentine, Tomoya Higo, Yusuke Nambu +5

NiGaS is a triangular lattice S=1 system with strong two-dimensionality of the lattice, actively discussed as a candidate to host spin-nematic order brought about by strong…

Terahertz conductivity of the magnetic Weyl semimetal MnSn films

Bing Cheng, Youcheng Wang, D. Barbalas +3

MnSn is a non-collinear antiferromagnet which displays a large anomalous Hall effect at room temperature. It is believed that the principal contribution to its anomalous Hall…

Large Spontaneous Hall Effects in Chiral Topological Magnets

S. Nakatsuji, T. Higo, M. Ikhlas +2

As novel topological phases in correlated electron systems, we have found two examples of non-ferromagnetic states that exhibit a large anomalous Hall effect. One is the chiral spi…

Frustrated magnetism in the Heisenberg pyrochlore antiferromagnets Yb ( = Cd, Mg, = S, Se)

Tomoya Higo, Kensuke Iritani, Mario Halim +5

Our polycrystalline sample study on the Yb-based chalcogenide spinels Yb ( Cd, Mg, S, Se) has revealed frustrated magnetism due to the antiferromagnetically…

Spin dynamics and spin freezing in the triangular lattice antiferromagnets FeGa2S4 and NiGa2S4

Songrui Zhao, P. Dalmas de R/'eotier, A. Yaouanc +6

Magnetic susceptibility and muon spin relaxation (muSR) experiments have been carried out on the quasi-2D triangular-lattice spin S = 2 antiferromagnet FeGa2S4. The muSR data indic…

Evidence for an exotic magnetic transition in the triangular spin system FeGa2S4

P. Dalmas de Reotier, A. Yaouanc, D. E. MacLaughlin +8

We report positive muon spin relaxation measurements on the triangular lattice magnetic system FeGa2S4. A magnetic transition not previously detected by specific heat and magnetic…
