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…
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…
Anomalous diamagnetism of electride electrons in transition metal silicides
M. Hiraishi, K. M. Kojima, H. Okabe +5
Intermetallic silicide compounds, LaScSi and YSi, known for being hydrogen (H) storage materials, are drawing attention as candidates for electrides in which anions are sub…
Polaronic nature of a muonium-related paramagnetic center in SrTiO
T. U. Ito, W. Higemoto, A. Koda +1
The hyperfine features and thermal stability of a muonium (Mu)-related paramagnetic center were investigated in the SrTiO perovskite titanate via muon spin rotation spectroscop…
Local Electronic Structure of Interstitial Hydrogen in Iron Disulfide
H. Okabe, M. Hiraishi, S. Takeshita +3
The electronic structure of interstitial hydrogen in a compound semiconductor FeS (naturally -type) is inferred from a muon study. An implanted muon (Mu, a pseudo-hydrogen)…
Electronic correlation in the quasi-two-dimensional electride YC
M. Hiraishi, K. M. Kojima, I. Yamauchi +10
Magnetic properties of the electride compound YC were investigated by muon spin rotation and magnetic susceptibility on two samples with different form (poly- and single-crysta…
Excited configurations of hydrogen in the BaTiOH perovskite lattice associated with hydrogen exchange and transport
T. U. Ito, A. Koda, K. Shimomura +4
Excited configurations of hydrogen in the oxyhydride BaTiOH (), which are considered to be involved in its hydrogen transport and exchange processes, were in…
Cage Electron-Hydroxyl Complex State as Electron Donor in Mayenite
M. Hiraishi, K. M. Kojima, M. Miyazaki +6
It is inferred from the chemical shift of muon spin rotation (SR) spectra that muons implanted in pristine (fully oxidized) mayenite, [CaAlO[$\square_…
Coexistence of Supercondcutivity and Magnetism in LaFeAs(O0.94F0.06) Probed by Muon Spin Relaxation
