The upper critical field in the BiCh2-based superconductors CeOBiS1.7Se0.3 and PrO0.5F0.5BiS2-xSex (x = 0, 0.3)
Ryosuke Kiyama, Kazuhisa Hoshi, Yosuke Goto +2
We report the upper critical field (Bc2) in the BiCh2-based superconductors CeOBiS1.7Se0.3 and PrO0.5F0.5BiS2-xSex (x = 0, 0.3). Single crystals of CeOBiS1.7Se0.3 and PrO0.5F0.5BiS…
Improvement of upper critical field by the compositionally-complex-alloy concept in A15 superconductor V3X (X: Al, Si, Ga, Ge, Sn)
Yuki Nakahira, Ryosuke Kiyama, Aichi Yamashita +5
Compositionally complex alloys (CCAs) are a new category of high-entropy materials containing more than two high-entropy phases in an alloy sample. We applied the concept of CCA to…
Superconductivity in In-doped AgSnBiTe3 with possible band inversion
Tsubasa Mitobe, Kazuhisa Hoshi, Md. Riad Kasem +9
We investigated the chemical pressure effects on structural and electronic properties of SnTe-based material using partial substitution of Sn by Ag0.5Bi0.5, which results in lattic…
Investigation of superconducting properties and possible nematic superconductivity in self-doped BiCh2-based superconductor CeOBiS1.7Se0.3
Ryosuke Kiyama, Kazuhisa Hoshi, Yosuke Goto +1
We investigate the superconducting properties and possible nematic superconductivity of self-doped BiCh2-based (Ch: S, Se) superconductor CeOBiS1.7Se0.3 through the measurements of…
Bulk superconductivity induced by Se substitution in self-doped BiCh2-based compound CeOBiS2-xSex
Ryosuke Kiyama, Yosuke Goto, Kazuhisa Hoshi +7
We report the Se substitution effects on the crystal structure, superconducting properties, and valence states of self-doped BiCh2-based compound CeOBiS2-xSex. Polycrystalline CeOB…
