Multipole polaron in the devil's staircase of CeSb
Y. Arai, Kenta Kuroda, T. Nomoto +17
Rare-earth intermetallic compounds exhibit rich phenomena induced by the interplay between localized orbitals and conduction electrons. However, since the energy scale of the c…
Appearance of ferromagnetism in Pt(100) ultrathin films originated from quantum-well states
Tatsuru Yamada, Keisuke Ochiai, Hirofumi Kinoshita +5
Ferromagnetism was observed in a Pt(100) ultrathin film deposited on a SrTiO3(100) substrate. The ferromagnetism, which appears in films with thicknesses of 2.2-4.4 nm, periodicall…
Observation of small Fermi pockets protected by clean CuO2 sheets of a high-Tc superconductor
So Kunisada, Shunsuke Isono, Yoshimitsu Kohama +15
The superconductivity of high transition temperature (Tc) occurs in copper oxides with carrier-doping to an antiferromagnetic (AF) Mott insulator. This discovery more than thirty y…
Structural phase diagram of LaO1-xFxBiSSe: suppression of the structural phase transition by partial F substitutions
Kazuhisa Hoshi, Shunsuke Sakuragi, Takeshi Yajima +5
We have investigated low-temperature crystal structure of BiCh2-based compounds LaO1-xFxBiSSe (x = 0, 0.01, 0.02, 0.03, and 0.5), in which anomalous two-fold-symmetric in-plane ani…
Devil's staircase transition of the electronic structures in CeSb
Kenta Kuroda, Y. Arai, N. Rezaei +21
Solids with competing interactions often undergo complex phase transitions with a variety of long-periodic modulations. Among such transition, devil's staircase is the most complex…
Material design with the van der Waals stacking of bismuth-halide chains realizing a higher-order topological insulator
Ryo Noguchi, Masaru Kobayashi, Zhanzhi Jiang +28
The van der Waals (vdW) materials with low dimensions have been extensively studied as a platform to generate exotic quantum properties. Advancing this view, a great deal of attent…
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…
Spintronic superconductor in a bulk layered material with natural spin-valve structure
Shunsuke Sakuragi, S. Sasaki, R. Akashi +29
Multi-layered materials provide fascinating platforms to realize various functional properties, possibly leading to future electronic devices controlled by external fields. In part…
Three-dimensional electronic structure in ferromagnetic with breathing kagome bilayers
Hiroaki Tanaka, Yuita Fujisawa, Kenta Kuroda +9
A large anomalous Hall effect (AHE) has been observed in ferromagnetic with breathing kagome bilayers. To understand the underlying mechanism for this,…
