Development and application of a He Neutron Spin Filter at J-PARC
T. Okudaira, T. Oku, T. Ino +22
We are developing a neutron polarizer with polarized He gas, referred to as a He spin filter, based on the Spin Exchange Optical Pumping (SEOP) for polarized neutron scatte…
Ultralow thermal conductivity from transverse acoustic phonon suppression in distorted crystalline α-MgAgSb
Xiyang Li, Peng-Fei Liu, Enyue Zhao +16
Low thermal conductivity is favorable for preserving the temperature gradient between the two ends of a thermoelectric material in order to ensure continuous electron current gener…
Phase transition in CaFeAsH: bridging 1111 and 122 iron-based superconductors
Yoshinori Muraba, Soshi Iimura, Satoru Matsuishi +5
Iron-based superconductors can be categorized as two types of parent compounds by considering the nature of their temperature-induced phase transitions; namely, first order transit…
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…
High-resolution structure studies and magnetoelectric coupling of relaxor multiferroic Pb(FeNb)O
Hasung Sim, Darren C. Peets, Sanghyun Lee +6
Pb(FeNb)O (PFN), one of the few relaxor multiferroic systems, has a -type antiferromagnetic transition at = 143 K and a ferroelectric transition at $T_…
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…
Local Lattice Distortion Caused by Short Range Charge Ordering in LiMnO
Katsuaki Kodama, Naoki Igawa, Shin-ichi Shamoto +5
We have performed powder neutron diffraction on Li-enriched sample of LiMnO at 300 K. The crystal structure determined by Rietveld analysis is a cubic spinel with space…
