Oxidation State of Cobalt in the NaxCoO2-d yH2O Superconductor
Maarit Karppinen, Isao Asako, Teruki Motohashi +1
Here we present results of accurate wet-chemical redox analyses, revealing that the oxidation number of cobalt in the newly discovered CoO2-layer superconductor, NaxCoO2 yH2O (x ~…

Kinetics and thermodynamics of the degree of order of the B cations in double-perovskite Sr2FeMoO6
T. Shimada, J. Nakamura, T. Motohashi +2
Here we show that the B-site cation (Fe/Mo) ordering in the double-perovskite magnetoresistor, Sr2FeMoO6, is controlled by either kinetics or thermal equilibrium depending on the t…

Sodium and oxygen nonstoichiometry and thermoelectric properties of NaxCoO2+d
T. Motohashi, M. Karppinen, H. Yamauchi
The sodium-cobalt oxide NaxCoO2+d is a promising candidate for thermoelectric applications since it may possess simultaneously large thermoelectric power and low resistivity. It is…
