Abstract

A series of sodium potassium cobalt oxyhydrates Na_xK _z(H₂O)_yCoO₂ (x=0.38-0.28 and z=0-0.08) were synthesized using aqueous KMnO₄ solution with various molar ratio of KMnO₄/Na with respect to the sodium content in the parent compound γ-Na_0.7CoO₂. Superconductivity was observed at the transition temperature T_c ∼ 4.5 - 4.6 K. in all fully-hydrated samples.
