Doping-induced topological transition and enhancement of thermopower in the Dirac-semimetal system CdZnAs
J. Fujioka, M. Kriener, D. Hashizume +3
CdAs is one of the prototypical topological Dirac semimetals. Here, we manipulate the band inversion responsible for the emergence of Dirac nodes by alloying CdAs w…
S=1/2 quantum critical spin ladders produced by orbital ordering in Ba2CuTeO6
A. S. Gibbs, A. Yamamoto, A. N. Yaresko +10
The ordered hexagonal perovskite Ba2CuTeO6 hosts weakly coupled S=1/2 spin ladders produced by an orbital ordering of Cu2+. The magnetic susceptibility chi(T) of Ba2CuTeO6 is well…
Epitaxially stabilized iridium spinel oxide without cations in the tetrahedral site
Hiromichi Kuriyama, Jobu Matsuno, Seiji Niitaka +7
Single-crystalline thin film of an iridium dioxide polymorph Ir2O4 has been fabricated by the pulsed laser deposition of LixIr2O4 precursor and the subsequent Li-deintercalation us…
Anomalous metallic state in the vicinity of Metal to Valence Bond Solid insulator transition in LiVS2
N. Katayama, M. Uchida, D. Hashizume +9
We investigate LiVS2 and LiVSe2 with a triangular lattice as itinerant analogues of LiVO2, known for the formation of valence bond solid (VBS) state out of S = 1 frustrated magnet.…
Metal-insulator Transition in a Pyrochlore-type Ruthenium oxide, Hg2Ru2O7
Ayako Yamamoto, Peter A. Sharma, Yoshihiko Okamoto +5
A new pyrochlore ruthenium oxide, Hg2Ru2O7 was synthesized under a high pressure of 6 GPa. In contrast to the extensively studied Ru4+ oxides, this compound possesses a novel Ru5+…
