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…
Topology meets time-reversal symmetry breaking in FeSeTe superconductor
M. Roppongi, Y. Cai, K. Ogawa +21
Time-reversal symmetry breaking (TRSB) in magnetic topological insulators induces a Dirac gap in the topological surface state (TSS), leading to exotic phenomena such as the quantu…
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…
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…
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…
Observation of superconductivity and enhanced upper critical field of -carbide-type oxide ZrPdO
Yuto Watanabe, Akira Miura, Chikako Moriyoshi +2
We report the first observation of bulk superconductivity of a -carbide-type oxide ZrPdO. The crystal structure and the superconducting properties were studied throu…
Synchrotron powder X-ray diffraction and structural analysis of Eu0.5La0.5FBiS2-xSex
K. Nagasaka, G. Jinno, O. Miura +4
Eu0.5La0.5FBiS2-xSex is a new BiS2-based superconductor system. In Eu0.5La0.5FBiS2-xSex, electron carriers are doped to the BiS2 layer by the substitution of Eu by La. Bulk superco…
