Impurity effects on Nax CoO2 · y H2 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 μeff = 3.20 μB. The induced local moment could lead to magnetic pair-breaking and is likely to be responsible for the Tc suppression by Mn impurities in Nax Co1 - z Mnz O2 · y H2 O.
