Electron -value comparison of paramagnetic muonium and hydrogen centers in rutile TiO
T. U. Ito, W. Higemoto, A. Koda
Muonium (Mu) is widely used as a model for isolated hydrogen in condensed matter, but whether its electronic state is truly equivalent to that of hydrogen remains to be tested with…
Persistent spin dynamics in magnetically ordered honeycomb cobalt oxides
Ping Miao, Xianghong Jin, Weiliang Yao +7
In the quest to find quantum spin liquids, layered cobalt oxides Na2Co2TeO6 and Na3Co2SbO6 have been proposed as promising candidates for approximating the Kitaev honeycomb model.…
Na-ion Dynamics in the Solid Solution NaCaCrO Studied by Muon Spin Rotation and Neutron Diffraction
Elisabetta Nocerino, Ola K. Forslund, Hiroya Sakurai +11
In this work we present systematic set of measurements carried out by muon spin rotation/relaxation (SR) and neutron powder diffraction (NPD) on the solid solution Na$_{\rm x}…
Local electronic structure of interstitial hydrogen in MgH inferred from muon study
R. Kadono, M. Hiraishi, H. Okabe +2
Magnesium hydride has great potential as a solid hydrogen (H) storage material because of its high H storage capacity of 7.6 wt%. However, its slow hydrogenation and dehydrogenatio…
Organic Molecular Dynamics and Charge-carrier Lifetime in Lead Iodide Perovskite MAPbI
A. Koda, H. Okabe, M. Hiraishi +4
The long charge carrier lifetime of the hybrid organic-inorganic perovskites (HOIPs) is the key for their remarkable performance as a solar cell material. The microscopic mechanism…
Pyrochlore Oxide Hg2Os2O7 on Verge of Metal-Insulator Boundary
Kota Kataoka, Daigorou Hirai, Akihiro Koda +3
Semimetallic osmium pyrochlore oxide Cd2Os2O7 undergoes a magnetic transition to an all-in-all-out (AIAO)-type order at 227 K, followed by a crossover to an AIAO insulator at aroun…
