Abstract

C(T) of NaxCo0.99Mn0.01O2 · yH2O is studied to reveal more details on the nature of the doped Mn ions and the Tc suppression. The extra specific heat contribution in NaxCo0.99Mn0.01O2 · yH2O manifests the induced local magnetic moment due to Mn doping. The absence of the superconducting transition peak in C(T) of NaxCo0.99Mn0.01O2 · yH2O suggests a reduced superconducting volume fraction.
