Superconductivity in Ternary Zirconium Telluride Zr6RuTe2
Kosuke Yuchi, Haruka Matsumoto, Daisuke Nishio-Hamane +5
Zr6CoAl2-type Zr6RuTe2 is found to show bulk superconductivity below the superconducting transition temperature Tc = 1.1 K, according to the electrical resistivity, magnetization,…
Anisotropic superconducting gap probed by Te NMR in noncentrosymmetric ScTe ( = Fe, Co)
Kanako Doi, Hayase Takei, Yusaku Shinoda +6
The superconducting gap symmetry is investigated by Te NMR measurements on ScTe ( = Fe, Co) without spatial inversion symmetry. The spin susceptibility obtained…
Tailoring the normal and superconducting state properties of ternary scandium tellurides, ScTe ( Fe, Ru and Ir) through chemical substitution
J. N. Graham, K. Yuchi, V. Sazgari +10
The pursuit of a unifying theory for non-BCS superconductivity has faced significant challenges. One approach to overcome such challenges is to perform systematic investigations in…
Broken time-reversal symmetry detected by tunneling spectroscopy of superconducting Pd-doped CaAgP
Naoki Matsubara, Rikizo Yano, Kazushige Saigusa +4
The appearance of broken time-reversal symmetry (TRS) in superconducting states is an intriguing issue in solid-state physics because of the incompatibility of the spontaneous magn…
Superconductivity in Hexagonal Zr6CoAl2-Type Zr6RuBi2 and Zr6FeBi2
Kosuke Yuchi, Daisuke Nishio-Hamane, Keita Kojima +3
We report the synthesis and electronic properties of polycrystalline samples of Zr6MBi2 (M = Ru and Fe) crystallizing in the hexagonal Zr6CoAl2-type structure. Based on their elect…
Superconductivity in Ternary Zirconium Telluride Zr6MTe2 with 3d Transition Metals
Haruka Matsumoto, Youichi Yamakawa, Ryutaro Okuma +2
We report the synthesis, electronic properties, and electronic states of Zr6MTe2 (M = Cr, Mn, Fe, and Co), which is isostructural to a recently discovered superconductor family Sc6…
