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... -
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... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
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... -
Na order and diffusion in NaxCoO2: Part II

Linking lattice dynamics and polymorphism in promising cathode materials for ...
Layered sodium transition metal oxides, NaMO2 (M = Fe, Co etc.), are a promising class of cathode materials for applications in sodium ion These materials exhibits complex but... -
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...
