Abstract

Within the t-J model, the heat transport of electron-doped cobaltates is studied based on the fermion-spin theory. It is shown that the temperature dependent thermal conductivity is characterized by the low temperature peak located at a finite temperature. The thermal conductivity increases monotonously with increasing temperature at low temperatures T << 0.1JJ, and then decreases with increasing temperature for higher temperatures T >> 0.1JJ, in qualitative agreement with experimental result observed from Nax_{x}CoO2_{2} .
