Successive Symmetry Breaking in a Jeff = 3/2 Quartet in the Spin-Orbit Coupled Insulator Ba2MgReO6
Daigorou Hirai, Zenji Hiroi
We report on the cubic double perovskite Ba2MgReO6 containing Re6+ ions with the 5d1 electron configuration. Resistivity, magnetization, and heat capacity measurements using single…
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…
One-dimensionalization by Geometrical Frustration in the Anisotropic Triangular Lattice of the 5d Quantum Antiferromagnet Ca3ReO5Cl2
Daigorou Hirai, Kazuhiro Nawa, Mitsuaki Kawamura +2
We report on the emergence of antiferromagnetic spin chains from two-dimensionally aligned spins on the anisotropic triangular lattice (ATL) in the insulating calcium rhenium oxych…
