Ultrasonic Observation of Slowing Down of Multipole Fluctuations in SrRuO
Ryosuke Kurihara, Mitsuhiro Akatsu, Shunsuke Yaoita +5
We performed ultrasonic measurements on the unconventional superconductor SrRuO to investigate the dynamical properties of the electronic states near its superconducting tr…
Search for magnetoacoustic quantum oscillations in the insulating phase of YbB
Ryosuke Kurihara, Atsuhiko Miyata, Koji Araki +9
A highly exotic phenomenon in solid-state physics is the observation of magnetic quantum oscillations in insulators. For instance, in the Kondo insulator YbB various groups…
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…
