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 magneto-optical imaging of superconducting critical states beyond 10 T using a paramagnetic garnet sensor
Yuto Kinoshita, Masayuki Toyoda, Yoshiaki Kobayashi +2
Spatially resolved characterization of the critical current density Jc in superconductors under high magnetic fields is crucial for both fundamental understanding and practical app…
Symmetry-resolved magnetoelastoresistance in multivalley bismuth
Suguru Hosoi, Fumu Tachibana, Mai Sakaguchi +6
We report a symmetry-resolved study of longitudinal magnetoelastoresistance (MER) in the multivalley material bismuth, with the current, uniaxial stress, and magnetic field all app…
Novel Easy-Axis Switching through Metamagnetism in CeSb
Atsushi Miyake, Ryuta Hayasaka, Hiroto Fukuda +9
A novel magnetic field-induced switching of the magnetization easy axis has been discovered in the layered compound CeSb, which crystallizes in an orthorhombic structure with n…
Removal of excess iron by annealing processes and emergence of bulk superconductivity in sulfur-substituted FeTe
Ryosuke Kurihara, Ryusuke Kogure, Tomotaka Ota +4
There are several strategies to discover new superconductors. Growing new materials and applying high pressures can be the classic ways since superconductivity was found. Also, che…
Direct Observation of Vortices and Antivortices Generation in Phase-Separated Superconductor Sn-Pb Solder
Hiroto Arima, Takumi Murakami, Yuto Kinoshita +4
Quantized vortices in type-II superconductors provide insights into the mechanisms of superconductivity. However, the generation of antivortices, characterized by magnetization ant…
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…
