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.
