Superconductivity in High-Entropy Antimonide MPtSb (M = equimolar Ru, Rh, Pd, and Ir)
Daigorou Hirai, Naoto Uematsu, Koh Saitoh +2
The high-entropy concept was applied to the synthesis of transition-metal antimonides, M1-xPtxSb (M = equimolar Ru, Rh, Pd, and Ir). High-entropy antimonide samples crystallized in…
Structural and Electronic Properties of a Triangular Lattice Magnet NaPrTe Compared with NaNdTe and NaTbTe
Koki Eto, Yoshihiko Okamoto, Naoyuki Katayama +3
NaPrTe2, NaNdTe2, and NaTbTe2 are found to be triangular lattice magnets with the alpha-NaFeO2 structure, where lanthanoid atoms with 4f electrons form a triangular lattice, based…
Superconductivity in Ternary Scandium Telluride Sc6MTe2 with 3d, 4d, and 5d Transition Metals
Yusaku Shinoda, Yoshihiko Okamoto, Youichi Yamakawa +3
We report the discovery of bulk superconductivity in Sc6MTe2 with seven kinds of transition-metal elements M. The critical temperatures for M = 3d elements are higher than those fo…
Large Magnetic-Field-Induced Strains in Sintered Chromium Tellurides
Yuki Kubota, Yoshihiko Okamoto, Tomoya Kanematsu +3
Sintered samples of Cr3Te4 and Cr2Te3 are found to show large strains accompanied by large volume changes under a magnetic field. In Cr3Te4, volume increases of deltaV/V = 500-1170…
Electronic Properties of Pyrochlore-Type Ca2Ir2O7
Yuki Nakayama, Yoshihiko Okamoto, Daigorou Hirai +1
The electrical resistivity, magnetic susceptibility, and heat capacity of sintered samples of Ca2Ir2O7, in which pentavalent Ir atoms with 5d4 electron configuration form a pyrochl…
Large Magnetic-Field-Induced Strain at the Spin-Reorientation Transition in the A-Site Ordered Spinel Oxide LiFeCr4O8
Yoshihiko Okamoto, Tomoya Kanematsu, Yuki Kubota +2
Sintered samples of a spinel oxide LiFeCr4O8, where Cr3+ and Fe3+ ions have localized moments, were found to show a large magnetic-field-induced volume increase approaching 500 ppm…
