摘要: | Impurity effects on NaxCoO2 (.) yH(2)O are studied by Mn doping. Spectroscopic evidence reveals that the doped Mn ions occupy the Co sites and the valence is +4. The magnetic local moment induced by Mn doping was observed and mu(eff) 3: 20 mB. The induced local moment could lead to magnetic pair-breaking and is likely to be responsible for the Tc suppression by Mn impurities in Na(x)Co(1-z)MnzO(2) (.) yH(2)O. (c) 2006 Elsevier B. V.
