Abstract

We argue that the spin fluctuations that give rise to superconductivity in Nax CoO2 · y H2 O and the 3D magnetism in the non-hydrated Nax CoO2 share the same origin. Due to the local minimum of the a1 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.
