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…
Spin accumulation at nonmagnetic interface induced by direct Rashba Edelstein effect
Florent Auvray, Jorge Puebla, Mingran Xu +3
Rashba effect describes how electrons moving in an electric field experience a momentum dependent magnetic field that couples to the electron angular momentum (spin). This physical…
Critical enhancement of thermopower in a chemically tuned polar semimetal MoTe
H. Sakai, K. Ikeura, M. S. Bahramy +5
Ferroelectrics with spontaneous electric polarization play an essential role in today's device engineering, such as capacitors and memories. Their physical properties are further e…
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+…
