Field-tunable Weyl points and large anomalous Hall effects in degenerate magnetic semiconductor EuMgBi
M. Kondo, M. Ochi, R. Kurihara +10
Magnets, with topologically-nontrivial Dirac/Weyl points, have recently attracted significant attention owing to the unconventional physical properties, such as large anomalous Hal…
Anomalous Nernst Effect in Nonmagnetic Nodal Line Semimetal PbTaSe
K. Yokoi, H. Murakawa, H. Sakai +1
PbTaSe is a unique topological material, in which the number of nodal lines is expected to change at the structural transition between the lower temperature/pressure "L" phase…
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…
