Magnetism and spin entropy in Ru doped Na 0.5 CoO 2

The effect of Ru doping on the magnetic coupling among Co ions and on the Seebeck effect in Na CoO was systematically studied using density functional theory. It was found that the Ru dopant takes the 4+ oxidation state and replaces a Co ion. In addition, the remaining Co ions in Na CoO :Ru were sta...
