Large Thermoelectric Power Factor in Whisker Crystals of Solid Solutions of the One-Dimensional Tellurides Ta4SiTe4 and Nb4SiTe4
Yuma Yoshikawa, Taichi Wada, Yoshihiko Okamoto +2
One-dimensional tellurides Ta4SiTe4 and Nb4SiTe4 were found to show high thermoelectric performance below room temperature. This study reported the synthesis and thermoelectric pro…
Electrical and Thermal Transport Properties of the beta-Pyrochlore Oxide CsW2O6
Yoshihiko Okamoto, Kenta Niki, Rikuto Mitoka +1
We report the electrical resistivity, thermoelectric power, and thermal conductivity of single-crystalline and sintered samples of the 5d pyrochlore oxide CsW2O6. The electrical re…
High-Mobility Carriers Induced by Chemical Doping in the Candidate Nodal-Line Semimetal CaAgP
Yoshihiko Okamoto, Kazushige Saigusa, Taichi Wada +7
We report the electronic properties of single crystals of candidate nodal-line semimetal CaAgP. The transport properties of CaAgP are understood within the framework of a hole-dope…
Regular-Triangle Trimer and Charge Order Preserving the Anderson Condition in the Pyrochlore Structure of CsWO
Yoshihiko Okamoto, Haruki Amano, Naoyuki Katayama +14
Since the discovery of the Verwey transition in magnetite, transition metal compounds with pyrochlore structures have been intensively studied as a platform for realizing remarkabl…
Thermal Expansion and Volume Magnetostriction in Breathing Pyrochlore Magnets LiACrX (A = Ga, In, X = O, S)
Tomoya Kanematsu, Masaki Mori, Yoshihiko Okamoto +2
We report thermal expansion and magnetostriction in breathing pyrochlore magnets LiACrX (A = Ga, In, X = O, S) measured by a dilatometric method on sintered samples. All fo…
Real spin and pseudospin topologies in the noncentrosymmetric topological nodal-line semimetal CaAgAs
Hishiro T. Hirose, Taichi Terashima, Taichi Wada +4
We present the topology of spin-split Fermi surface of CaAgAs as determined by de Haas-van Alphen (dHvA) effect measurements combined with ab initio calculations. We have determine…
