Abstract
We compute specific heat of the antiferromagnetic spin- Heisenberg model on the kagome lattice. We use a recently introduced technique to analyze high-temperature series expansion based on the knowledge of high-temperature series expansions, the total entropy of the system and the low-temperature expected behavior of the specific heat, as well as the ground-state energy. In the case of the kagome-lattice antiferromagnet, this method predicts a low-temperature peak at .
