Helical Edge Transport in the ν= 0 Quantum Hall Ferromagnetic State of an Organic Dirac Fermion System
Toshihito Osada, Mitsuyuki Sato, Takako Konoike +1
We experimentally confirm the ν= 0 quantum Hall ferromagnetic (QHF) state, accompanied by helical edge states, in the layered organic Dirac-fermion system α-(ET)2I3 by demonstratin…
Quantized thermoelectric Hall plateau in the quantum limit of graphite as a nodal line semimetal
Andhika Kiswandhi, Tomotaka Ochi, Toshihiro Taen +3
We performed thermoelectric Hall conductivity measurements on single-crystal graphite in the quantum limit up to 13 T. Both electrical and thermoelectric transport measure…
Experimental Confirmation of Massive Dirac Fermions in Weak Charge-Ordering State in α-(BEDT-TTF)_2I_3
Kenta Yoshimura, Mitsuyuki Sato, Toshihito Osada
The electronic structure of weak charge-ordering (CO) state just below the critical pressure in an organic conductor α-(BEDT-TTF)_2I_3 was experimentally investigated using peak st…
Experimental Confirmation of Quantum Hall Ferromagnetic State in an Organic Dirac Fermion System
Mitsuyuki Sato, Takako Konoike, Toshihito Osada
We have experimentally confirmed the quantum Hall ferromagnetic state with Chern number ν=0, characterized by the helical edge state, in a layered organic Dirac fermion system α-(B…
Anisotropy of Dirac cones and van Hove singularity in an organic Dirac fermion system
Ayaka Mori, Mitsuyuki Sato, Takeshi Yajima +3
We propose an experimental method to examine the in-plane anisotropy of electronic structure in layered conductors. In the method, we measure the interlayer magnetoresistance as a…
Spin and Valley Splittings in Multilayered Massless Dirac Fermion System
N. Tajima, M. Sato, S. Sugawara +3
The inter-layer magnetoresistance in a multilayered massless Dirac fermion system, -(BEDT-TTF)I, under hydrostatic pressure was investigated. We succeeded in detecting t…
