Abstract

C(T) of Na_xCo_0.99Mn_0.01O₂ · yH₂O is studied to reveal more details on the nature of the doped Mn ions and the T_c suppression. The extra specific heat contribution in Na_xCo_0.99Mn_0.01O₂ · yH₂O manifests the induced local magnetic moment due to Mn doping. The absence of the superconducting transition peak in C(T) of Na_xCo_0.99Mn_0.01O₂ · yH₂O suggests a reduced superconducting volume fraction.
