YCr6Ge6 as a Candidate Compound for a Kagome Metal
Yui Ishii, Hisatomo Harima, Yoshihiko Okamoto +2
We show that YCr6Ge6, comprising a kagome lattice made up of Cr atoms, is a plausible candidate compound for a kagome metal that is expected to exhibit anomalous phenomena such as…
Complex Orbital State Stabilized by Strong Spin-Orbit Coupling in a Metallic Iridium Oxide IrO
Yasuyuki Hirata, Kenya Ohgushi, Jun-ichi Yamaura +4
Resonant x-ray diffraction experiments were performed for the metallic iridium oxide IrO. We observed anisotropic tensor of susceptibility (ATS) scattering, the spectrum of w…
Large Diamagnetism of AV2Al20 (A = Y and La)
Atsushi Onosaka, Yoshihiko Okamoto, Jun-Ichi Yamaura +2
We find anomalously large diamagnetic responses in the cage compounds AV2Al20 where A = Y and La, not A = Al0.3, Sc0.4, and Lu, despite the apparent similarities in crystal and ele…
Rattling and Superconducting Properties of the Cage Compound GaxV2Al20
Zenji Hiroi, Atsushi Onosaka, Yoshihiko Okamoto +2
Low-energy rattling modes and their effects on superconductivity are studied in the cage compound GaxV2Al20. A series of polycrystalline samples of 0 < x =< 0.6 are examined throug…
A novel crystal polymorph of volborthite, Cu3V2O7(OH)2 2H2O
Hajime Ishikawa, Jun-ichi Yamaura, Yoshihiko Okamoto +3
A new polymorph of volborthite [tricopper(II) divanadium(V) heptaoxide dihydroxide dihydrate], Cu3V2O7(OH)2 2H2O, has been discovered in a single crystal prepared by hydrothermal s…
Tetrahedral Magnetic Order and the Metal-Insulator Transition in the Pyrochlore Lattice of Cd2Os2O7
J. Yamaura, K. Ohgushi, H. Ohsumi +11
Cd2Os2O7 shows a peculiar metal-insulator transition at 227 K with magnetic ordering in a frustrated pyrochlore lattice, but its magnetic structure in the ordered state and the tra…
