Stabilizing Itinerant Electrons in a Corner-Sharing Kagomé Oxide Nd4Os3ZnO14
Ryutaro Okuma, Yuita Fujisawa, Chia-Hsiu Hsu +8
Kagome oxides provide a fertile platform for exploring exotic electronic states arising from geometrical frustration and characteristic band topology. Here, we report the synthesis…
Molecular Orbital Degeneracy Lifting in a Tetrahedral Cluster System NbSeI
Keita Kojima, Youichi Yamakawa, Ryutaro Okuma +6
The lifting of degenerate electronic states, in which multiple electronic states share the same energy, is a fundamental issue in the physics of crystalline solids. In real materia…
Superconductivity in Ternary Zirconium Telluride Zr6RuTe2
Kosuke Yuchi, Haruka Matsumoto, Daisuke Nishio-Hamane +5
Zr6CoAl2-type Zr6RuTe2 is found to show bulk superconductivity below the superconducting transition temperature Tc = 1.1 K, according to the electrical resistivity, magnetization,…
Cubic ReSTe as a High-Performance Thermoelectric Material
Haruka Matsumoto, Hiroto Isomura, Keita Kojima +5
We report thermoelectric properties of sintered samples of undoped, W-doped, and Sb-doped ReSTe crystallized in a cubic MoSBr-type structure. All samples exhibited p-type thermoele…
Topological Electronic Structure and Transport Properties of the Distorted Rutile-type WO
Yuto Muramatsu, Daigorou Hirai, Mitsuaki Kawamura +6
We elucidate the transport properties and electronic structures of distorted rutile-type WO2. Electrical resistivity and Hall effect measurements of high-quality single crystals re…
