Abstract

It was found that Na+ ions in NaxCoO2 can be partially substituted by H3O+ ions while maintaining a constant Co valence simply by immersion in water. The magnetic susceptibility of Nax(H3O)zCoO2 (x + Z = 0.70) changed drastically from Curie-Weiss type to Pauli paramagnetic type, indicating that the electronic band structure was modified by the isovalent ion substitution of Na+/H3O+. Two possible origins of the change in the electronic structure are discussed.
