Non-linear transport in field-induced insulating states of graphite
Masashi Tokunaga, Kazuto Akiba, Hiroshi Yaguchi +2
Graphite exhibits multi-stage phase transitions in the quantum-limit states realized by magnetic fields applied along the c-axis. Despite extensive studies on this phenomenon, the…
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…
