Na order and diffusion in NaxCoO2: Part II

DOI

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 temperature. We have recently presented muSR as a tool to study ion diffusion via the hopping rate (nu). Further, we have even more recently performed an initial experiment in ISIS where we successfully applied this method to study Na dynamics in NCO. Here we propose to continue this study over a wider range of sodium content (x). We are convinced that an improved understanding of the Na dynamics will not only provide key data for future battery materials, but could also help the general understanding of how ionic dynamics affects magnetic and electronic properties. For NCO in specific, a better comprehension of such modulation of electronic texture might be the route to an optimization of e.g. thermoelectric properties.
