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…
Superconductivity at 12 K in LaIOs: a 5d metal with osmium honeycomb layer
Hajime Ishikawa, Takeshi Yajima, Daisuke Nishio-Hamane +3
We discovered superconductivity at = 12 K in a layered compound LaIOs with osmium honeycomb network. Despite heavy constituent elements unfavorable for phonon mediate…
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…
Dimer Crystallization Induced by Elemental Substitution in the Honeycomb Lattice of Ru1-xOsxCl3
Kota Kataoka, Dirk Wulferding, Takeshi Yajima +5
Substitution effects of Os for Ru in α-RuCl3 are investigated in a wide composition range of 0 =< x =< 0.67 in Ru1-xOsxCl3 by X-ray and electron diffraction, magnetic susceptibilit…
Anomalous transport due to Weyl fermions in the chiral antiferromagnets Mn, = Sn, Ge
Taishi Chen, Takahiro Tomita, Susumu Minami +9
The recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn, ( = Sn, Ge) have brought the study of magnetic topological states to…
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…
Synthesis of anti-perovskite-type carbides and nitrides from metal oxides and melamine
Daigorou Hirai, Hidetake Tanaka, Daisuke Nishio-Hamane +1
Four anti-perovskite-type compounds, ZnNNi3, ZnCNi3, SnNCo3, and SnCCo3, are synthesised through reactions between ingredient metal oxides and organic compound melamine (C3H6N6). Z…
"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…
Giant anomalous Nernst effect and quantum-critical scaling in a ferromagnetic semimetal
Akito Sakai, Yo Pierre Mizuta, Agustinus Agung Nugroho +9
In metallic ferromagnets, the Berry curvature of underlying quasiparticles can cause an electric voltage perpendicular to both magnetization and an applied temperature gradient, a…
Large anomalous Nernst effect at room temperature in a chiral antiferromagnet
Muhammad Ikhlas, Takahiro Tomita, Takashi Koretsune +5
Temperature gradient in a ferromagnetic conductor may generate a spontaneous transverse voltage drop in the direction perpendicular to both magnetization and heat current. This ano…

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…
Semimetallic transport properties of epitaxially stabilized perovskite CaIrO3 films
Daigorou Hirai, Jobu Matsuno, Hidenori Takagi
We report on the synthesis and transport properties of perovskite (Pv) CaIrO3 thin films. The Pv phase of CaIrO3 was stabilized by epitaxial growth on SrTiO3, (LaAlO3)0.3(Sr2AlTaO6…
