Superconductivity in a Magnetic Rashba Semimetal EuAuBi
Hidefumi Takahashi, Kazuto Akiba, Masayuki Takahashi +4
We report the observation of superconductivity with multiple magnetic ordering and Rashba-type spin-orbit coupling in a layered polar semimetal EuAuBi. Magnetic transition is obser…
Possible helimagnetic order in Co4+-containing perovskites Sr1-xCaxCoO3
Hidefumi Takahashi, Masaho Onose, Yasuhito Kobayashi +7
We systematically synthesized perovskite-type oxides Sr1-xCaxCoO3 containing unusually high valence Co4+ ions by a high pressure technique, and investigated the effect of systemati…
Optical hyperpolarization of nitrogen donor spins in bulk diamond
M. Loretz, H. Takahashi, T. F. Segawa +2
We report hyperpolarization of the electronic spins associated with substitutional nitrogen defects in bulk diamond crystal. Hyperpolarization is achieved by optical pumping of nit…
Superconductivity at 52 K in hydrogen-substituted LaFeAsO1-xHx under high pressure
Hiroki Takahashi, Hideto Soeda, Muga Nukii +6
The 1111-type iron-based superconductor LnFeAsO1-xFx (Ln stands for lanthanide) is the first material with a Tc above 50 K, other than cuprate superconductors. Electron doping into…
