Ultrasonic observation of small Fermi surfaces in LaIn ( = Co, Rh, Ir)
Ryosuke Kurihara, Yusuke Hirose, Kazuki Matsui +8
We performed high-field ultrasonic measurements on LaIn ( = Co, Rh, Ir) to reveal the origin of the small Fermi surface that was recently observed in LaRhIn with an o…
Effects of successive annealing on high-field electrical transport and the upper critical field in S-substituted FeTe
Ryosuke Kurihara, Satoshi Hakamada, Masaki Kondo +3
Since iron-based superconductors have been discovered, many scientists have focused on their characteristic properties, such as an unconventional mechanism and a high upper critica…
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…
Emergence of ferroelectric topological insulator as verified by quantum Hall effect of surface states in (Sn,Pb,In)Te films
Ryutaro Yoshimi, Ryosuke Kurihara, Yoshihiro Okamura +9
Emergent phenomena arising from nontrivial band structures based on topology and symmetry have been attracting keen interest in contemporary condensed-matter physics. Materials suc…
