Local electronic structure of dilute hydrogen in $β$ -MnO $_{2}$

H. Okabe, M. Hiraishi, A. Koda +7

The electronic and magnetic states of $β$ -MnO $_{2}$ in terms of hydrogen impurities have been investigated by muon spin rotation ( $μ$ SR) technique combined with density-functional…

Photo-excited charge carrier lifetime enhanced by slow cation molecular dynamics in lead iodide perovskite FAPbI $_{3}$

M. Hiraishi, A. Koda, H. Okabe +4

Using muon spin relaxation ( $μ$ SR) measurements on formamidinium lead iodide [FAPbI $_{3}$ , where FA denotes HC(NH $_{2})_{2}$ ] we show that, among the five structurally distinct phases of…
