Raman spectroscopy of van der Waals topological magnet GdGaI
Nan Jiang, Yijin Zhang, Yujie Xia +9
We report polarization-resolved Raman spectroscopy of a van der Waals compound GdGaI that is a candidate for excitonic insulators. By combining the symmetry analysis with density f…
Crystal structure built from a GeO-GeO polyhedra network with high thermal stability: -SrGeO
Christian A. Niedermeier, Jun-ichi Yamaura, Jiazhen Wu +4
By tackling the challenge of extending transparent oxide semiconductors to Ge based oxides, we have found a not-yet-reported crystal structure, named -SrGeO, which is co…
Semimetallic "Electride Bands" Derived from Interlayer Electrons in Quasi-Two-Dimensional Electride YC
Koji Horiba, Ryu Yukawa, Taichi Mitsuhashi +10
Two-dimensional (2D) electrides are a new concept material in which anionic electrons are confined in the interlayer space between positively charged layers. We have performed angl…
All-in/all-out magnetic domains: X-ray diffraction imaging and magnetic field control
Samuel Tardif, Soshi Takeshita, Hiroyuki Ohsumi +5
Long-range non-collinear all-in/all-out magnetic order has been directly observed for the first time in real space in the pyrochlore CdOsO using resonant magnetic micro…
Hydrogen Ordering and New Polymorph of Layered Perovskite Oxyhydrides: Sr2VO4-xHx
Joonho Bang, Satoru Matsuishi, Haruhiro Hiraka +7
Compositionally tunable vanadium oxyhydrides Sr2VO4-xHx (x = 0 - 1) without considerable anion vacancy were synthesized by high-pressure solid state reaction. The crystal structure…
Layered Compounds BaM2Ge4Ch6 (M = Rh, Ir and Ch = S, Se) with Pyrite-Type Building Blocks and Ge-Ch Heteromolecule-Like Anions
Hechang Lei, Jun-ichi Yamaura, Jiangang Guo +3
Structure and chemical features of layered compounds BaM2Ge4Ch6 (M = Rh, Ir; Ch = S, Se) synthesized under high-pressure and high-temperature method are systematically studied. The…
Novel Rattling of K Atoms in Aluminium-Doped Defect Pyrochlore Tungstate
Elvis Shoko, Gordon J Kearley, Vanessa K Peterson +5
Rattling dynamics have been identified as fundamental to superconductivity in defect pyrochlore osmates and aluminium vanadium intermetallics, as well as low thermal conductivity i…
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…
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…
Crystal Chemistry and Magnetic Properties of Manganese Zinc Alloy "YMn2Zn20" Comprising a Mn Pyrochlore Lattice
Yoshihiko Okamoto, Takeshi Shimizu, Jun-ichi Yamaura +1
The chemical composition, crystal structure, and magnetic properties of a manganese zinc alloy with an ideal composition of YMn2Zn20, which comprises a pyrochlore lattice made of M…
