Abstract

We argue that the spin fluctuations that give rise to superconductivity in Na_x CoO₂ · y H₂ O and the 3D magnetism in the non-hydrated Na_x CoO₂ share the same origin. Due to the local minimum of the a_{1 g} band at the Γ point, inner and outer portions of the Fermi surface arise, where the nesting between the two results in these interesting phenomena.
