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…
