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…
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…
Magnetic Order in the Spin-1/2 Kagome Antiferromagnet Vesignieite
Makoto Yoshida, Yoshihiko Okamoto, Masashi Takigawa +1
We report results of magnetic susceptibility and 51V- and 63,65Cu-NMR measurements on a high-quality powder sample of vesignieite BaCu3V2O8(OH)2, a candidate for the spin-1/2 kagom…
Spin reorientation in the square-lattice antiferromagnets RMnAsO (R = Ce, Nd): Density functional analysis of the spin exchange interactions between the rare-earth and transition-metal ions
Changhoon Lee, Erjun Kan, Hongjun Xiang +4
The spin reorientation (SR) phenomenon of the square-lattice antiferromagnets RMnAsO (R = Ce, Nd) was investigated by analyzing the spin exchange interactions between the rare-eart…
