Abstract [en]

The internal magnetic field in a sodium battery compound, i.e., the paramagnet Na0.7CoO2, was investigated with negative muon spin rotation and relaxation (mu-SR), and the result was compared with the results previously obtained with mu+SR. The majority of implanted mu(-) is captured on an oxygen nucleus, while mu(+) locates an interstitial site. Therefore, a mu(+/-) SR work provides information on the internal magnetic field, which is formed by nuclear magnetic moments of Na-23 and Co-59, from the two different viewpoints. Besides a slight decrease in the field distribution width (Delta) around 300 K, the nuclear magnetic field detected with mu- SR was found to be almost static and temperature independent up to 400 K, even though Na ions are known to start to diffuse above 290 K based on mu(+) SR, Na-NMR, neutron scattering, and electrochemical measurements. Such a discrepancy is caused by the fact that the Na contribution to Delta is only about 3% at the O site whereas it is about 13% at the interstitial site, where the mu(+) is presumably located.
