Electronic Properties of Pyrochlore-Type Ca2Ir2O7
Yuki Nakayama, Yoshihiko Okamoto, Daigorou Hirai +1
The electrical resistivity, magnetic susceptibility, and heat capacity of sintered samples of Ca2Ir2O7, in which pentavalent Ir atoms with 5d4 electron configuration form a pyrochl…
Dimensional reduction and incommensurate dynamic correlations in the triangular-lattice antiferromagnet CaReOCl
S. A. Zvyagin, A. N. Ponomaryov, J. Wosnitza +7
The observation of spinon excitations in the triangular antiferromagnet CaReOCl reveals a quasi-one-dimensional (1D) nature of magnetic correlations, in…
Extremely large magnetoresistance in the hourglass Dirac loop chain metal β-ReO
Daigorou Hirai, Takahito Anbai, Shinya Uji +2
The transport and thermodynamic properties of -ReO crystallizing in a nonsymmorphic structure were studied using high-quality single crystals. An extremely large magnetore…
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…
Possible quadrupole order in tetragonal Ba2CdReO6 and chemical trend in the ground states of 5d1 double perovskites
Daigorou Hirai, Zenji Hiroi
The synthesis and physical properties of the double perovskite (DP) compound Ba2CdReO6 with the 5d1 electronic configuration are reported. Three successive phases originating from…
Kitaev Spin Liquid Candidate OsxCl3 Comprised of Honeycomb Nano-Domains
K. Kataoka, D. Hirai, T. Yajima +11
An osmium chloride with the chemical formula of OsxCl3 (x = 0.81) was synthesized and its crystal structure and thermodynamic properties were investigated. OsxCl3 crystallizes in a…
