Direct observation of a spin-polarized surface Dirac gap in the antiferromagnetic topological insulator NdBi
Yuto Fukushima, Hiroyuki S. Suzuki, Masayuki Ochi +15
A gapped Dirac cone in antiferromagnetic topological insulators (AFM-TIs) is essential for realizing the quantized anomalous Hall effect, yet its intrinsic magnitude remains contro…
High-Field Terahertz Spin Resonance in CrO above the Spin-Flop Transition
Kaiyang Huang, Yuto Kinoshita, Natsuki Kanda +4
We report single-shot terahertz time-domain spectroscopy of CrO in pulsed magnetic fields up to 30 T. Well above the spin-flop field, in the 20-30 T range, the resonance fr…
High-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Yuhao Ye, Akiyoshi Yamada, Yuto Kinoshita +16
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twi…
Low-temperature hysteresis broadening emerging from domain-wall creep dynamics in a two-phase competing system
Keisuke Matsuura, Yo Nishizawa, Yuto Kinoshita +6
Hysteretic behaviour accompanies any first-order phase transition, forming a basis for many applications. However, its quantitative understanding remains challenging, and even a qu…
Effects of strain-tunable valleys on charge transport in bismuth
Suguru Hosoi, Fumu Tachibana, Mai Sakaguchi +6
The manipulation of the valley degree of freedom can boost the technological development of novel functional devices based on valleytronics. The current mainstream platform for val…
Pseudogap and Fermi arc induced by Fermi surface nesting in a centrosymmetric skyrmion magnet
Yuyang Dong, Yuto Kinoshita, Masayuki Ochi +12
Skyrmions in noncentrosymmetric materials are believed to occur due to the Dzyaloshinskii-Moriya interaction. By contrast, the skyrmion formation mechanism in centrosymmetric mater…
Observation of nonvolatile magneto-thermal switching in superconductors
Hiroto Arima, Md. Riad Kasem, Hossein Sepehri-Amin +5
Applying a magnetic field to a solid changes its thermal-transport properties. Although such magneto-thermal-transport phenomena are usually small effects, giant magneto-thermal re…
