Journal ArticleDOI
Superconducting properties of MgB2 bulk materials prepared by high-pressure sintering
Yoshihiko Takano,Hiroyuki Takeya,Hiroki Fujii,Hiroaki Kumakura,Takeshi Hatano,Kazumasa Togano,Hijiri Kito,Hideo Ihara +7 more
TL;DR: In this paper, high-density bulk materials of a recently discovered 40 K intermetallic MgB2 superconductor were prepared by high-pressure sintering, and the superconducting transition with the onset temperature of 39 K was confirmed by both magnetic and resistive measurements.
Journal ArticleDOI
S-wave spin-triplet order in superconductors without inversion symmetry: Li2Pd3B and Li2Pt3B.
Huiqiu Yuan,Daniel F. Agterberg,Nobuhiko Hayashi,Petre Badica,D. Vandervelde,Kazumasa Togano,Manfred Sigrist,M. B. Salamon +7 more
TL;DR: It is proposed that broken inversion symmetry and the accompanying antisymmetric spin-orbit coupling, which admix spin-singlet and spin-triplet pairing, are responsible for this behavior of noncentrosymmetric superconductors Li2Pd3B andLi2Pt3B.
Journal ArticleDOI
Superconductivity in the metal rich Li-Pd-B ternary boride.
TL;DR: Structural, microstructural, electrical, and magnetic investigations for various compositions proved that the Li2Pd3B compound, which has an antiperovskite cubic structure composed of distorted Pd6B octahedrons, is responsible for the superconductivity.
Journal ArticleDOI
Partial Melt Growth Process of Bi2Sr2Ca1Cu2Ox Textured Tapes on Silver
Junichiro Kase,Kazumasa Togano,Hiroaki Kumakura,Daniel R. Dietderich,Naoshi Irisawa,Takeshi Morimoto,Hiroshi Maeda +6 more
TL;DR: Bi2Sr2Ca1Cu2Ox textured tapes with an excellent Jc were synthesized by doctor-blade casting and a melt process as mentioned in this paper, where green tape was laid on a silver foil and oxide/silver composite tape was heat treated.
Journal ArticleDOI
Evidence for a multiple superconducting gap in MgB(2) from high-resolution photoemission spectroscopy.
Syunsuke Tsuda,Takayoshi Yokoya,Takayuki Kiss,Yoshihiko Takano,Kazumasa Togano,Hijiri Kito,Hideo Ihara,Shik Shin +7 more
TL;DR: High-resolution photoemission spectroscopy of the new binary intermetallic superconductor MgB(2) shows a coherent peak with a shoulder structure, and temperature-dependent study shows that both gaps close at the bulk transition temperature.
