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…
A large moment antiferromagnetic order in overdoped high-Tc superconductor 154SmFeAsO1-xDx
Soshi Iimura, Hiroshi Okanishi, Satoru Matsuishi +6
In iron-based superconductors, high critical temperature (Tc) superconductivity over 50 K has only been accomplished in electron-doped hREFeAsO (hRE = heavy rare earth (RE) element…
Hydrogen Ordering and New Polymorph of Layered Perovskite Oxyhydrides: Sr2VO4-xHx
Joonho Bang, Satoru Matsuishi, Haruhiro Hiraka +7
Compositionally tunable vanadium oxyhydrides Sr2VO4-xHx (x = 0 - 1) without considerable anion vacancy were synthesized by high-pressure solid state reaction. The crystal structure…
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…
Evidence for anisotropic polar nanoregions in relaxor PMN: A neutron study of the elastic constants and anomalous TA phonon damping
C. Stock, P. M. Gehring, H. Hiraka +6
We use neutron scattering to characterize the acoustic phonons in the relaxor PMN and demonstrate the presence of an anisotropic damping mechanism directly related to short-range,…
Progress in Neutron Scattering Studies of Spin Excitations in High-Tc Cuprates
Masaki Fujita, Haruhiro Hiraka, Masaaki Matsuda +5
Neutron scattering experiments continue to improve our knowledge of spin fluctuations in layered cuprates, excitations that are symptomatic of the electronic correlations underlyin…
