Quantum dynamics of hydrogen in iron-based superconductor LaFeAsO0.9D0.1 measured with inelastic neutron spectroscopy
Jun-ichi Yamaura, Haruhiro Hiraka, Soshi Iimura +13
Inelastic neutron scattering was performed for an iron-based superconductor LaFeAsO0.9D0.1, where most of D (deuterium) replaces oxygen, while a tiny amount goes into interstitial…
Pressure-induced quantum critical point in a heavily hydrogen-doped iron-based superconductor LaFeAsO
Masayoshi Takeuchi, Naoki Fujiwara, Takanori Kuwayama +6
An iron-based superconductor LaFeAsOH (0 0.6) undergoes two antiferromagnetic (AF) phases upon H doping. We investigated the second AF phase (=0.6) usi…
Experimental evidence of enhancement without the influence of spin fluctuations: NMR study on LaFeAsO_{1-x}H_x under a pressure of 3.0 GPa
N. Kawaguchi, N. Fujiwara, S. Iimura +2
The electron-doped high-transition-temperature (T_c) iron-based pnictide superconductor LaFeAsO_{1-x}H_x has a unique phase diagram: superconducting (SC) double domes are sandwiche…
Heavy Electron doping-induced antiferromagnetic phase as the parent for iron-oxypnictide superconductor LaFeAsO1-xHx
Soshi Iimura, Satoru Matsuishi, Hideo Hosono
We perform transport measurements and band structure calculations of electron-doped LaFeAsO1-xHx over a wide range of x from 0.01 to 0.66. The T^2 and sqrt(T) dependency of the res…
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…
Bipartite magnetic parent phases in the iron-oxypnictide superconductor
Masatoshi Hiraishi, Soshi Iimura, Kenji M. Kojima +19
High-temperature (high-) superconductivity appears as a consequence of the carrier-doping of an undoped parent compound exhibiting antiferromagnetic order; thereby, grou…
