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…
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…
Magnetic field effect on Fe-induced short-range magnetic correlation and electrical conductivity in BiPbSrCuFeO
S. Wakimoto, H. Hiraka, K. Kudo +8
We report electrical resistivity measurements and neutron diffraction studies under magnetic fields of BiPbSrCuFeO, in which ho…
Ni-Impurity Effects on Incommensurate Spin Correlations in Superconducting La2-xSrxCuO4 (x=0.06 and 0.07)
H. Hiraka, S. Ohta, S. Wakimoto +2
Neutron scattering experiments have been carried out to explore Ni-impurity effects on static spin correlations in La2-xSrxCuO4 (LSCO) in the vicinity of the superconductor-insulat…
Oxygen Phonon Branches in Detwinned YBa2Cu3O7
D. Reznik, L. Pintschovius, W. Reichardt +6
We report results of inelastic neutron scattering measurements of phonon dispersions on a detwinned sample of YBaCu3O7 and compare them with model calculations. Plane oxygen bond s…
Spin Pseudo Gap in La2-xSrxCuO4 Studied by Neutron Scattering
C. H. Lee, K. Yamada, H. Hiraka +2
Spin excitations of La2-xSrxCuO have been studied using inelastic neutron scattering techniques in the energy range of 2 meV =< w =< 12 meV and the temperature range of 8 K =< T =<…
Static and dynamic spin correlations in the spin-glass phase of slightly-doped La_{2-x}Sr_xCuO_4
M. Matsuda, M. Fujita, K. Yamada +6
Neutron scattering experiments reveal that a diagonal spin modulation, which is a one-dimensional modulation rotated away by 45 from that in the superconducting phase, occu…
