Abstract

Dynamics, structure and properties of sodium cobaltate (Na _xCoO ₂) class of compound are discussed. Such compounds are based on a triangular lattice of spin -1/2 ions where a high thermoelectric power Curie-Weiss metallic paramagnet is found. The basic structure of Na _xCoO ₂ is hexagonal and consist of robust layers of CoO ₂ interspersed by sodium (Na) layers with two inequivalent sites. It is also found that there is strong inverse correlation between the CoO ₂ layer thickness and the superconducting transition temperature.
