Transport evidence of current-induced nematic Dirac valleys in a parity-time-symmetric antiferromagnet
H. Sakai, Y. Miyamoto, M. Kimata +6
Itinerant antiferromagnets with broken time-reversal symmetry have recently attracted attention, since their spin-split bands enable large magnetotransport responses comparable to…
Nonreciprocal charge transport in polar Dirac metals with tunable spin-valley coupling
M. Kondo, M. Kimata, M. Ochi +7
Nonreciprocal charge transport in solids, where resistance is different between rightward and leftward currents, is a key function of rectifying devices in the modern electronics,…
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…
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…
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…
