Superconductivity induced by doping holes in the nodal-line semimetal NaAlGe
Toshiya Ikenobe, Takahiro Yamada, Daigorou Hirai +2
The nodal-line semimetals NaAlSi and NaAlGe have significantly different ground states despite having similar electronic structures: NaAlSi exhibits superconductivity below 7 K, wh…
Unusual Resistive Transitions in the Nodal-Line Semimetallic Superconductor NaAlSi
Daigorou Hirai, Toshiya Ikenobe, Takahiro Yamada +2
NaAlSi is a quasi-two-dimensional semimetal with superconductivity below Tc = 6.8 K and a band structure characterized by nodal lines near the Fermi level and potential topological…
Superconductivity in the Topological Nodal-line Semimetal NaAlSi
Takahiro Yamada, Daigorou Hirai, Hisanori Yamane +1
NaAlSi is an sp electron superconductor crystallizing in a layered structure of the anti-PbFCl type with a relatively high transition temperature Tc of ~7 K. Recent electronic stat…
Nematic transition and highly two-dimensional superconductivity in BaTiBiO revealed by Bi-nuclear magnetic resonance/nuclear quadrupole resonance measurements
Shunsaku Kitagawa, Kenji Ishida, Wataru Ishii +2
In this Rapid Communication, a set of Bi-nuclear magnetic resonance (NMR)/nuclear quadrupole resonance (NQR) measurements has been performed to investigate the physical pro…
Formation and Control of Twin Domains in the Pyrochlore Oxide Cd2Re2O7
Yasuhito Matsubayashi, Daigorou Hirai, Masashi Tokunaga +1
The successive phase transitions of the pyrochlore oxide Cd2Re2O7 are studied by polarizing microscopy and magnetic susceptibility measurements. The formation of twin domains is vi…
Pyrochlore Oxide Superconductor Cd2Re2O7 Revisited
Zenji Hiroi, Jun-ichi Yamaura, Tatsuo C. Kobayashi +2
The superconducting pyrochlore oxide Cd2Re2O7 is revisited with a particular emphasis on the sample-quality issue. The compound has drawn attention as the only superconductor (Tc =…
