Enhancing thermopower and Nernst signal of high-mobility Dirac carriers by Fermi level tuning in the layered magnet EuMnBi
Keigo Tsuruda, Kento Nakagawa, Masayuki Ochi +5
Dirac/Weyl semimetals hosting linearly-dispersing bands have received recent attention for potential thermoelectric applications, since their ultrahigh-mobility carriers could gene…
Tunable spin-valley coupling in layered polar Dirac metals
Masaki Kondo, Masayuki Ochi, Tatsuhiro Kojima +9
In non-centrosymmetric metals, spin-orbit coupling (SOC) induces momentum-dependent spin polarization at the Fermi surfaces. This is exemplified by the valley-contrasting spin pola…
Ta Nuclear quadrupole resonance study of non-centrosymmetric superconductor PbTaSe
K. Yokoi, M. Yashima, H. Murakawa +5
We report on a pure Ta-nuclear quadrupole resonance (NQR) measurement of PbTaSe at zero magnetic field, which has the advantage of directly probing the intrinsic superc…
Bulk quantum Hall effect of spin-valley-coupled Dirac fermions in a polar antiferromagnet BaMnSb
H. Sakai, H. Fujimura, S. Sakuragi +16
Unconventional features of relativistic Dirac/Weyl quasi-particles in topological materials are most evidently manifested in the 2D quantum Hall effect (QHE), whose variety is furt…
Large Enhancement of Thermoelectric Efficiency Due to a Pressure-Induced Lifshitz Transition in SnSe
T. Nishimura, H. Sakai, H. Mori +10
Lifshitz transition, a change in Fermi surface topology, is likely to greatly influence exotic correlated phenomena in solids, such as high-temperature superconductivity and comple…
Limits of Validity of Rashba Model in BiTeI: A High-field Magneto-optical Study
S. Bordacs, M. Orlita, M. Sikula +2
It was recently shown that BiTeI, a semiconductor with polar crystal structure, possesses a giant spin-splitting of electrons, which has been interpreted in terms of Rashba-type sp…
