Linear Trimer Formation by Three-Center-Four-Electron Bonding in RuP
Daigorou Hirai, Keita Kojima, Naoyuki Katayama +3
In molecules like hydrogen, most chemical bonds are formed by sharing two electrons from each atom in the bonding molecular orbital (two-center-two-electron (2c2e) bonding). There…
Magnetic ordering in the = 0 Nickelate NiRhO prepared via a solid-state metathesis
Yuya Haraguchi, Daisuke Nishio-Hamane, Hiroko Aruga Katori
In spinel-type nickelate NiRhO, magnetic ordering is observed upon the sample synthesized via kinetically controlled low-temperature solid-state metathesis, as opposed to p…
SmI3: 4f5 honeycomb magnet with spin-orbital entangled Γ7 Kramers doublet
Hajime Ishikawa, Ryosuke Kurihara, Takeshi Yajima +5
We report magnetic properties of a 4f-honeycomb iodide SmI3 made up of edge-shared network of SmI6 octahedra. High temperature magnetic susceptibility indicates Γ7 Kramers doublet…
Spin-orbit-coupled metal candidate PbRe2O6
Satoshi Tajima, Daigorou Hirai, Takeshi Yajima +3
We study the lead rhenium oxide PbRe2O6 as a candidate spin-orbit-coupled metal (SOCM), which has attracted much attention as a testing ground for studying unconventional Fermi liq…
Contrasted Sn Substitution effects on Dirac line node semimetals SrIrO and CaIrO
Masamichi Negishi, Naoka Hiraoka, Daisuke Nishio-Hamane +1
Perovskite-type iridates SrIrO and CaIrO are a Dirac line node semimetal protected by crystalline symmetry, providing an interesting playground to investigate electron…
"Visible" 5d orbital states in a pleochroic oxychloride
Daigorou Hirai, Takeshi Yajima, Daisuke Nishio-Hamane +7
Transition metal compounds sometimes exhibit beautiful colors. We report here on a new oxychloride Ca3ReO5Cl2 which shows unusually distinct pleochroism; that is, the material exhi…
Weak ferromagnetic order breaking the threefold rotational symmetry of the underlying kagomé lattice in CdCu(OH)(NO)HO
Ryutaro Okuma, Takeshi Yajima, Daisuke Nishio-Hamane +2
Novel magnetic phases are expected to occur in highly frustrated spin systems. Here we study the structurally perfect kagomé antiferromagnet CdCu(OH)(NO)HO…
