Ion dynamics in Sodium and Potassium Cobalt Dioxides
We found that muSR detects Li-diffusion in LixCoO2, LiNiO2, Lix(NiCoMn)O2 and LiFePO4 through a dynamic behavior of nuclear field relaxation. Very recently, we have also found... -
Li diffusion in Li-Mn-O (continuation)
This proposal describes a continuation muSR experiment on Li-Mn-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing... -
Na order and diffusion in NaxCoO2: Part II
Recently there have been reports that high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at low... -
Doping-induced energy gap in a quantum spin chain
SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless... -
Diffusive behavior in battery materials under electric field
Lithium diffusion in magnetic materials is found to be well detected by muon-spin spectroscopy. However, such a diffusive behavior has been measured without potential gradient,... -
Na order and diffusion in NaxCoO2: a route to tuning of thermoelectric & magn...
Recently there have been many reports on how high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at... -

Recently there have been reports that high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at low... -
Li diffusion in charged state Lix(Ni1/3Co1/3Mn1/3)O2
This proposal describes a muSR experiment on Li-deficient Lix(Ni1/3Co1/3Mn1/3)O2 to determine a Li diffusion coefficient as a function of the Li content x, because muSR is a... -
Probing the random singlet state in antiferromagnetic Heisenberg spin chain c...
Low-dimensional quantum spin systems with introduced disorder are a fascinating playground for investigations of the interplay between quantum effects, strong correlations and... -
Li diffusion in Li-Mn-O
This proposal describes a muSR experiment on Li-Mn-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing magnetic ions.... -
Diffusive behavior in garnet-type Li ion conductor under electric field
This proposal describes a muSR experiment on a garnet-type Li ionic conductor, Li6.75La3Zr1.75Nb0.25O12 under electric field (E) in order to study a diffusive behavior under a... -
Comparative study on Li diffusion in Li-Ti-oxides by muSR and NMR
This proposal describes a muSR experiment on Li-Ti-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing magnetic ions.... -
Ion dynamics in Potassium Ordered & Disordered KxCoO2
We have recently presented a novel method to study ion-dynamics in solids using muSR via the hopping rate (nu). We have previously and successfully applied this method to study...
