Distinct Roles of Hydrogen in Superconducting and Ferromagnetic Phases of CoZrH
Yuto Watanabe, Takayoshi Katase, Daisuke Takegami +1
Hydrogenation offers a versatile route to tuning the physical properties of intermetallic compounds. In this study, we synthesized CoZrH with different hydrogen content…
Uniaxial negative thermal expansion in a weak-itinerant-ferromagnetic phase of CoZrH
Yuto Watanabe, Kota Suzuki, Takayoshi Katase +3
We discovered unique uniaxial negative thermal expansion (NTE) behavior for a weak-itinerant-ferromagnetic phase of CoZrH. CoZr is known as a superconductor ex…
Diffusion-Controlled Anion Conversion into Dense Polycrystalline and Single-Crystalline Oxyhydrides
Masaya Fujioka, Mihiro Hoshino, Suguru Iwasaki +8
Oxyhydrides represent a new class of functional materials, yet the synthesis of dense polycrystals or single-crystals suitable for transport studies remains a significant challenge…
Specific heat analyses on optical-phonon-derived uniaxial negative thermal expansion system Zr ( = Fe and CoNi)
Yuto Watanabe, Ceren Tayran, Md. Riad Kasem +4
Recently, huge uniaxial negative thermal expansion (NTE) along a -axis has been observed in transition-metal () zirconides Zr with a tetragonal CuAl-type str…
High entropy effect on thermoelectric properties of nonequilibrium cubic phase of AgBiSe2-2xSxTex with x = 0-0.6
Asato Seshita, Aichi Yamashita, Takayoshi Katase +1
Silver bismuth diselenide (AgBiSe2) has much attention as an efficient thermoelectric material due to its low thermal conductivity. However, AgBiSe2 exhibits multiple crystal struc…
Stabilization and high thermoelectric performance of high-entropy-type cubic AgBi(S, Se, Te)2
Asato Seshita, Aichi Yamashita, Takeshi Fujita +6
As thermoelectric generators can convert waste heat into electricity, they play an important role in energy harvesting. The metal chalcogenide AgBiSe2 is one of the high-performanc…
