GdV6Sn6: a Multi-carrier Metal with Non-magnetic 3d-electron Kagome Bands and 4f-electron Magnetism
Hajime Ishikawa, Takeshi Yajima, Mitsuaki Kawamura +2
Electronic properties of the single crystal of GdV6Sn6, where non-magnetic V-kagome layers are separated by magnetic Gd-triangular lattice, are investigated. GdV6Sn6 exhibits uniqu…
Anisotropic Triangular Lattice Realized in Rhenium Oxychlorides A3ReO5Cl2 (A = Ba and Sr)
Daigorou Hirai, Takeshi Yajima, Kazuhiro Nawa +2
We report the synthesis, crystal structure, and magnetic properties of two new quantum antiferromagnets A3ReO5Cl2 (A = Sr and Ba). The crystal structure is isostructural with the m…
Methods for constructing parameter-dependent flat band lattices
Toshitaka Ogata, Mitsuaki Kawamura, Taisuke Ozaki
We present two methods for constructing a flat band (FB) system having a flat energy dispersion over the entire Brillouin zone within tight-binding model, where the resulting Hamil…
