Geometrical Hall effect and momentum-space Berry curvature from spin-reversed band pairs
Max Hirschberger, Yusuke Nomura, Hiroyuki Mitamura +10
When nanometric, noncoplanar spin textures with scalar spin chirality (SSC) are coupled to itinerant electrons, they endow the quasiparticle wavefunctions with a gauge field, terme…
Magneto-transport properties of tellurium under extreme conditions
Kazuto Akiba, Kaya Kobayashi, Tatsuo C. Kobayashi +5
This study investigates the transport properties of a chiral elemental semiconductor tellurium (Te) under magnetic fields and pressure. Application of hydrostatic pressure reduces…
Capacitive detection of magnetostriction, dielectric constant, and magneto-caloric effects in pulsed magnetic fields
Atsushi Miyake, Hiroyuki Mitamura, Shiro Kawachi +5
We report on the development of a capacitance measuring system which allows measurements of capacitance in pulsed magnetic fields up to 61~T. By using this system, magnetic-field r…
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…
