= 1/2 Hyperoctagon Lattice in Cobalt Oxalate Metal-Organic-Framework
Hajime Ishikawa, Shusaku Imajo, Hikaru Takeda +4
We report the magnetic properties of a cobalt oxalate metal-organic-framework featuring the hyperoctagon lattice. Our thermodynamic measurements reveal the = 1/2 sta…
Geometric frustration and Dzyaloshinskii-Moriya interactions in a quantum star lattice hybrid copper sulfate
Hajime Ishikawa, Yuto Ishii, Takeshi Yajima +6
We study the magnetism of a layered, spin- organic-inorganic copper sulfate, which is a close realization of the star lattice antiferromagnet, one of the playgrounds of ge…
Fermi surface and light quasi particles in hourglass nodal chain metal \b{eta}-ReO2
Daigorou Hirai, Takahito Anbai, Takako Konoike +8
Quantum oscillations in magnetic torque and electrical resistivity were measured to investigate the electronic structure of \b{eta}-ReO2, a candidate hourglass nodal chain metal (D…
Structural and Electronic Properties of a Triangular Lattice Magnet NaPrTe Compared with NaNdTe and NaTbTe
Koki Eto, Yoshihiko Okamoto, Naoyuki Katayama +3
NaPrTe2, NaNdTe2, and NaTbTe2 are found to be triangular lattice magnets with the alpha-NaFeO2 structure, where lanthanoid atoms with 4f electrons form a triangular lattice, based…
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…
Emergence of nontrivial magnetic excitations in a spin liquid state of kagome volborthite
Daiki Watanabe, Kaori Sugii, Masaaki Shimozawa +7
When quantum fluctuations destroy underlying long-range ordered states, novel quantum states emerge. Spin-liquid (SL) states of frustrated quantum antiferromagnets, in which highly…
