Uncovering hidden Fermi surface instabilities through visualizing unconventional quasiparticle interference in CeTe3
B. R. M. Smith, Y. Fujisawa, P. Wu +14
The charge density wave (CDW) state is a widespread phenomenon in low-dimensional metals/semimetals. The spectral weight of the associated folded bands (shadow bands) can be an int…
Superconductivity in Hexagonal Zr6CoAl2-Type Zr6RuBi2 and Zr6FeBi2
Kosuke Yuchi, Daisuke Nishio-Hamane, Keita Kojima +3
We report the synthesis and electronic properties of polycrystalline samples of Zr6MBi2 (M = Ru and Fe) crystallizing in the hexagonal Zr6CoAl2-type structure. Based on their elect…
Selective synthesis and crystal chemistry of candidate rare earth Kitaev materials: honeycomb and hyperhoneycomb NaPrO
Ryutaro Okuma, Kylie MacFarquharson, Radu Coldea
Rare earth oxides have attracted interest as a platform for studying frustrated magnetism arising from bond dependent anisotropic interactions. Ordered rock salt compounds NaPr…
Compass-model physics on the hyperhoneycomb lattice in the extreme spin-orbit regime
Ryutaro Okuma, Kylie MacFarquharson, Roger D. Johnson +3
The physics of spin-orbit entangled magnetic moments of and transition metal ions on a honeycomb lattice has been much explored in search for unconventional magnetic orde…
Emergent topological magnetism in Hund's excitonic insulator
R. Okuma, K. Yamagami, Y. Fujisawa +14
Analogous to the charged electron-electron pair condensation in superconductors, an excitonic insulator (EI) represents Fermi surface instability due to spontaneous formation and c…
Superconductivity in Ternary Zirconium Telluride Zr6MTe2 with 3d Transition Metals
Haruka Matsumoto, Youichi Yamakawa, Ryutaro Okuma +2
We report the synthesis, electronic properties, and electronic states of Zr6MTe2 (M = Cr, Mn, Fe, and Co), which is isostructural to a recently discovered superconductor family Sc6…
