摘要

Impurity effects on Na_x 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 μ_eff = 3.20 μ_B. The induced local moment could lead to magnetic pair-breaking and is likely to be responsible for the T_c suppression by Mn impurities in Na_x Co_{1 - z} Mn_z O₂ · y H₂ O.
