Investigation of superconducting gap of high-entropy telluride AgInSnPbBiTe5
Asato Seshita, Hirotaka Okabe, Riad Kasem +9
We performed transverse-field muon spin relaxation/rotation (TF-μSR) on a high-entropy-type (HE-type) superconductor AgInSnPbBiTe5. The emergence of bulk superconducting states was…
Nonvolatile magneto-thermal switching driven by vortex trapping in commercial In-Sn solder
Poonam Rani, Takumi Murakami, Yuto Watanabe +4
Magneto-thermal switching (MTS) is a key technology for efficient thermal management. Recently, large MTS with nonvolatility has been observed in Sn-Pb solders [H. Arima et al., Co…
Influence of trapped magnetic field of Sn-Pb solders on electrical resistivity measurement: an example of superconducting transition of Sn
Takumi Ichikawa, Yuto Watanabe, Takumi Murakami +3
We examined the affection of the flux-trapped states of Sn60-Pb40 solders on superconducting properties of a Sn wire. The temperature dependence of electrical resistivity at H = 0…
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…
Superconducting properties and electronic structure of CuAl2-type transition-metal zirconide Fe1-xNixZr2
Ryunosuke Shimada, Yuto Watanabe, Lorenzo Tortora +8
CuAl2-type transition-metal (Tr) zirconides are superconductor family, and the Tr-site element substitution largely modifies its transition temperature (Tc). Here, we synthesized p…
Vortex formation and exotic superconducting states in field-cooled Sn-Pb solders
Takumi Murakami, Md. Riad Kasem, Hiroto Arima +3
Formation of vortices is a typical phenomenon of type-II superconductors under magnetic fields (H). In contrast, type-I superconductors do not host vortices because of their Meissn…
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…
