Anisotropic upper critical field in the van der Waals superconducting quasicrystal (TaNb)Te
Koki Kasai, Yuki Tokumoto, Taichi Terashima +2
We investigated the upper critical field of a large single grain of the Nb-substituted van der Waals layered quasicrystal (TaNb)Te. The sample exhibits a sh…
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…
Nonlinear planar Hall effect from superconducting vortex motion
Mio Hashimoto, Takako Konoike, Tomoki Kobayashi +6
We report the nonreciprocal charge transport along the longitudinal and transverse directions in the vortex flow regime of FeSe superconducting films. Clear nonreciprocal signals u…
Multipolar Phase Transition in the 4 fcc lattice compound PrCdNi
Yuka Kusanose, Yasuyuki Shimura, Kazunori Umeo +10
Transport and magnetic properties of a 4 fcc lattice compound, PrCdNi, were studied. The magnetic susceptibility, , follows the Curie--Weiss law from 300 K to 20 K…
Anomalous upper critical field in the quasicrystal superconductor TaTe
Taichi Terashima, Yuki Tokumoto, Kotaro Hamano +3
Superconductivity in quasicrystals poses a new challenge in condensed matter physics. We measured the resistance and ac magnetic susceptibility of a TaTe dodecagonal quasic…

Daigorou Hirai, Takahito Anbai, Takako Konoike +8
Quantum oscillations in magnetic torque and electrical resistivity were measured to investigate the electronic structure of \b{eta}-ReO2, a candidate hourglass nodal chain metal (D…
Experimental verification of band convergence in Sr and Na codoped PbTe
Yuya Hattori, Shunsuke Yoshizawa, Keisuke Sagisaka +5
Scanning tunneling microscopy and transport measurements have been performed to investigate the electronic structure and its temperature dependence in heavily Sr and Na codoped PbT…
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…
Magnetization, thermoelectric, and pressure studies of the magnetic field-induced metal to insulator transition in tau phase organic conductors
D. Graf, E. S. Choi, J. S. Brooks +5
We have investigated the magnetic field-induced metal-insulator transition in the tau-phase organic conductors, which occurs in fields above 35 T, and below 14 K, by magnetization,…
