Relationship between local hydride ion dynamics and ionic conductivity in LaH${}_{3-2x}$O${}_x$ inferred from muon study

M. Hiraishi, S. Takeshita, H. Okabe +6

We performed muon spin rotation and relaxation ($\mu$SR) experiments to investigate the microscopic mechanism behind the high ionic conductivity ($\sigma$) exhibited by hydride (H${}^{-}$) io…
